Search and Destroy: The Brutal Vietnam War Tactics Used Between 1965 and 1967

 

In 1965, tens of thousands of US troops are  heading for war in Vietnam. Backed up by B-52   bombers, helicopters and napalm, many expect the  Viet Cong guerillas to crumble in the face of   unstoppable US firepower. Instead, in the jungles  and swamps of Vietnam, the Americans discover   combat is an exhausting slog in which casualties  are high and they rarely get to fire first.

In summer 1965, 50,000 US troops arrived in  South Vietnam as part of Military Assistance   Command Vietnam, MACV. The USA hopes American  troops and airpower will be enough to compel   North Vietnam to abandon its support of the Viet  Cong insurgency working to undermine the South   Vietnamese government. Still, the US approach will  be gradual and mostly from the air.

 By late 1964,   the US has already been secretly bombing North  Vietnamese supply lines in neighbouring Laos,   and in 1965 North Vietnam is hit as  part of Operation Rolling Thunder.  Still, the US mostly hits secondary targets –  not Hanoi – in order to force North Vietnam to   negotiate an agreement beneficial to the South.

  In this sense, US President Lyndon B Johnson is   not aiming for traditional territorial or total  victory, but the prevention of a North Vietnamese   victory over his allies in the South. North Vietnam claims no negotiations   can take place while foreign  troops remain in South Vietnam. And so, it seems combat, not compromise,  will be the status quo in Vietnam.

 US   General WIlliam Westmoreland needs to develop a  strategy to push the North out of South Vietnam   at a low cost for the US – politically  and militarily. This is a challenge,   since political considerations mean his ground war  must be confined almost entirely to South Vietnam. Johnson rules out any kind of conventional  invasion of North Vietnam as it will likely   provoke Chinese intervention, as it did during  the Korean War.

 The President also cutting the   Ho Chi Minh trail in Laos and Cambodia since  he wants to limit ground operations. This,   though, will make it harder for  Westmoreland to isolate the battlefield.  The American debate settles on two possible  strategies in South Vietnam: conventional   combat operations, or counterinsurgency focused  on small unit operations and the political   pacification of the South Vietnamese public.

 Although the counterinsurgency approach has   its supporters, Westmoreland believes it  requires more troops and gives the Viet Cong   the initiative. Instead, he hopes to make use of  the US advantages in mobility and firepower in a   strategy of annihilation. He plans to take  the fight to the Viet Cong, eliminate them   in large unit set piece battles, and cause such  heavy casualties North Vietnam cannot maintain the   insurgency. It’s a rapid attritional strategy.

 To achieve their goals, US troops will not   need to hold ground, but will carry out  “search and destroy” operations at will. “… This is going to be a methodical  search, house by house, village by village,   as we move north… This small group of  huts here houses some of the Vietnamese   families.

 We’re looking mostly today  for military age men that may possibly   be VC. So far all we can see are  women and children and old men…”  It’s a plan with an institutional shift in the  Department of Defense. Under Secretary Robert   McNamara, the DoD adopts new statistical and  quantitative management methods borrowed from   the world of business.

 Everything about the war  is quantified to assess progress and identify   when North Vietnam reaches the critical “tipping  point” when it can no longer sustain the struggle.  Analysts and officers count everything from bomb  tonnage to tent pegs, but the most important   metric is the ‘body count’ of North Vietnamese  and Viet Cong killed in US operations. Since the   US won’t judge progress by territory captured in  the same way as many traditional wars, the body   count will form the basis for analysing success.

  The Pentagon therefore encourages US commanders   to aim for higher kill and capture counts as  a means of realising Westmoreland’s strategy. The American kill count strategy expands  the original passive protective role of   the US troops, since now, they  are to go on offensive patrols   and take the fight to the Viet Cong. And  they’ll be doing it with new firepower.

In an ideal search and destroy operation  US troops identify a Viet Cong formation   via intelligence and reconnaissance and then  quickly insert ground troops to pin the enemy   down. As the battle intensifies and draws in  more enemy, the US troops call-in airstrikes   and artillery to decisively eliminate them.

 Similar operations had previously been carried   out by ARVN, but American commanders felt they  failed because the South Vietnamese troops’   lack of fighting quality, as opposed  to a problem with the actual tactics.  To support their efforts, US forces receive  new tools, vehicles and weapons. From 1964,   US army troops receive the 5.56mm M16 rifle to  replace the 7.62mm M14.

 The change will not always   prove popular, but the US military claims the M16  is lighter, more controllable in automatic and can   be carried with more ammunition – all important  features in jungle combat where ranges are   shorter and resupply harder. Coupled with the M60  machine gun and M79 “Thumper” grenade launchers,   US platoons expect to bring heavy firepower  against the more lightly armed Viet Cong.  

Perhaps the most important asset in a  platoon is the radio, which can call   in support from fire bases or aircraft. With much of South Vietnam consisting   of jungle-covered highlands or swampy deltas,  ground transport is slow to impossible. Instead,   a brown water navy of patrol boats and  hovercrafts navigate the rivers, while a   new generation of American military helicopters  provide unprecedented mobility.

 In particular,   the UH-1 Iroquois – or Huey – replaces the  cumbersome Shawnee to become the iconic   vehicle of the Vietnam War. Used for troop  insertions, extractions, medical evacuations,   resupply and fire support, around a third of the  36 million helicopter sorties flown during the   war are made by Hueys.

 US jet aircraft,  such as the F-4 Phantom and A-4 Skyhawk,   also arrive to provide rapid close air support,  including with napalm and white phosphorous, while   the multi-minigun equipped AC-47 ‘Spooky’ gunship  can provide overhead cover for hours at a time.  US helicopters have an early impact on combat.  During the Battle of Ia Drang in November 1965,   air assault troops inflict heavy casualties on  North Vietnamese regulars entering from Cambodia.  

Although the NVA launch some close-range assaults  at landing zones, US firepower pushes them back,   including the first tactical use of B-52  bombers. Although most of the NVA escapes,   the US 1st Air Cavalry Division claim a 10:1  kill ratio, seemingly confirming air assault   tactics and Westmoreland’s strategy.

 At first, the helicopters also have a   psychological impact on North Vietnamese  troops, as North Vietnamese soldier   Nguyen Quang Sang remembers: “…when helicopters spotted us,   we had to run for our lives. It was terrifying…  Once, when a helicopter dropped down especially   close… I even saw the face of the door  gunner.

 That was the first time I ever   saw an American. I’m still haunted by it  in my nightmares.” (Appy Patriots 216) By the end of 1965, the US can claim to have  prevented a South Vietnamese collapse and   taken the fight to the enemy. But the  Viet Cong also adapt, and fight back. The mauling at Ia Drang encourages the North  Vietnamese army and Viet Cong to turn back   to guerilla tactics.

 This is partly due to  practical considerations, but also a nuanced   understanding of the US political situation. North  Vietnamese General Secretary Le Duan recognises   US strength in Vietnam is undermined by a  lack of political and public will back home:  “[We] can fight a protracted war, while the  US can’t… although the US can immediately   send 300,000 to 400,00 troops at once,  why must the US do it step by step?…  

Because of fear of protracted war, and even  stronger opposition of the American people   and the world’s people…” (Ruane 110) Instead, the Viet Cong will take the lead   in the south and employ strategies which had  worked against ARVN. In 1963 US General Frank   Osmanski summarized on Viet Cong tactics: “VC non-explosive weapons include caltrops,   spike-traps, poisoned darts, and even  enraged water buffaloes.

 In a sense   their physical endurance, patience,  and ingenuity are also VC weapons,   for they have been known to live in dark tunnels  for weeks, to remain underwater for long periods   by breathing through hollow reeds, and to lie  in ambush for as long as 48 hours.” (Langer 75)  Sniping, mines and booby traps become the  principle means of Viet Cong attack.

 They   prioritize mines since they maim just as often  as they kill, draining US resources and morale.  The Viet Cong also become experts at launching  well-planned ambushes, often targeting officers   and radiomen to prevent air support being  called in. Most attacks are over in minutes.  These tactics are aided by simplified  logistics.

 A Viet Cong soldier carries   as less as five kilograms of equipment in combat,  compared to up to 40 for a US soldier. The North   Vietnamese can also draw on local supplies from  friendly or coerced villagers. Additionally,   they can blend into the local civilian  population and call on irregular supporters   who can perform labour, set mines, or collect  unexploded US ordnance for repurposing. 

Vast networks of tunnels, some even under US  bases, allow for the VC to infiltrate and protect   their personnel and equipment from US firepower. Parallel to the Viet Cong is the regular People’s   Army of Vietnam, also known as the North  Vietnamese Army, or NVA. Thanks to political   regimentation, propaganda and conscription,  the NVA quickly expands with new Soviet and   Chinese equipment.

 Soon NVA units can claim to  match US squad firepower with weapons like the   AK-47 automatic rifle, RPD machinegun, and rocket  propelled grenades. The Viet Cong are sometimes   armed with WWII-era weapons, but also receive  newer equipment via the Ho Chi Minh trail.  The Soviet Union and China also  provide protection against bombing,   including engineering troops, anti-aircraft  systems and fighter jets, such as MiG-21s.  

North Vietnamese fighter ace Luu Huy Chao  recalls one advantage he had over US pilots:  “Once I had shot down an F-4, I was no longer  scared of any type of American aircraft. The   psychological factor is very important in  any battle… part of my confidence came   from knowing that if I had to bail out I would be  landing in my own country.

” (Appy Patriots 214) The North Vietnamese approach is to attack only  when the situation favours them. As a result,   they often neutralise US technological advantages  through patience and surprise. In fact, although   helicopters dominate the news, the reality  of combat in Vietnam is decidedly low tech. One reason for this is that helicopters are  expensive and valuable targets for the Viet   Cong.

 Once familiar with helicopters, the North  Vietnamese become skilled at shooting them down   or targeting them at vulnerable moments. Their  loud rotors make surprise almost impossible,   allowing for ambushes at landing  zones with RPGs or heavy machine guns:  “When the troops leaped from the lead choppers,  the entire tree line erupted with small arms   f

ire… A machine gun opened up from the  hillside north of the LZ, pouring lethal   fire into the helicopters… The rounds went  smashing into the plexiglass cockpits… One   bird rolled over like a great wounded bull  elephant, the rotor blades still whirring as   they chopped into the earth…” (Langer 126) The US loses around 5,000 helicopters during   the war, about half to enemy action.

 To reduce the risk, helicopters drop   off US troops at more secure locations for long,  sometimes multi-week patrols in the jungle – known   to the GIs as “humping the boonies”. In these conditions, the Viet Cong are   only one adversary for the Americans. Wildlife,  mosquitos, disease, exhaustion and dehydration   affect US troops too.

 With only one percent of  patrols experiencing enemy contact, mines and   booby traps are perhaps the biggest concern. They  account for about a quarter of all casualties,   as one 19 year old US soldier reports: “It’s an absurd combination of certainly   and uncertainty: the certainty that you’re  walking in mine fields, walking past things   day after day; the uncertainty of your every  movement, of which way to shift your weight,   of where to sit down.

” (Appy WCW 171) When there is contact, the Viet Cong   almost always trigger the engagement with a 1966  report suggesting the North Vietnamese initiate   around 79 percent of attacks. They also become  skilled at predicting air support response times   and withdrawing before it arrives, or attacking  so close that air support threatens US troops   as well. By 1968, around 15 to 20 percent  of US casualties are from friendly fire.

“As you come into the village you always  get this sniper fire, never fails. And,   we invariably take casualties once in a while.  We return fire, and by the time we get to the   villages, these VC are gone, and it makes it  very difficult and very frustrating for us.” US weapons also struggle in the jungle  environment, especially the M16 rifle.

 A US   study records 10.5 malfunctions per 1,000 rounds  fired in 1965. Overall, the M16’s lightweight   materials were sensitive to variations  in propellant and poor lubrication – and   many US soldiers who arrive early on had no prior  training with the M16 before arriving in Vietnam.  Eventually the Pentagon introduces modifications,  like rust resistant components, along with better   maintenance training. By 1968 the M16’s  malfunction rate declines to around 3.

8   malfunctions per 1,000 rounds, with the  most serious ejection failures reduced   to 0.32. Still, its early reputation  persists, especially amongst Marines.  The M60 machine-gun also has its supporters  and detractors. When functioning, troops value   its versatility and morale-building firepower –  including when mounted on helicopters.

 But others   note its reliability quickly declines through wear  and tear, with few replacement parts available.   Its high rate of fire also requires riflemen  to carry heavy 7.62 ammunition and barrels.  Overall, this mixture of combat stress,  physical exhaustion, danger and inability to   fight back creates frustration among US soldiers: “You go out on patrol maybe twenty times or more,   and nothin’, just nothin’.

 Then, the  twenty-first time, zap, zap, zap, you   get hit and Victor Charlie fades into the jungle  before you can close with him.” (Lawrence TVW 107) US troops in Vietnam are also under many  additional stresses. Around a quarter are   draftees – essentially conscripts  – and their average age is only 19. Few of the American newcomers transfer to  Vietnam as complete units, but instead arrive   as individuals or in small groups.

 High officer  turnover and the fact few experienced troops stay   beyond their contracted tour of duty means combat  experience is not retained and must be relearned.  The stresses of combat, an elusive enemy, and  peer pressure might partly explain – though not   excuse – how cases of American violence against  Vietnamese civilians become widespread. As the   war continues, civilians suffer increasing  violence, injury and property destruction,   both intentional and accidental, at the hands  of US, ARVN and allied troops.

 Hostility – or   at least ambivalence – from locals leads  some US GIs to conclude villagers support   the Viet Cong. In many cases, this is true  – even a South Vietnamese government report   estimates 5 million of the 17 million residents  of South Vietnam support the insurgency.  This realisation undermines US soldiers’  belief in the war, and promotes indifference   to the plight of locals.

 Marine officer  Phillip Caputo is one who lost hope:  “…When we marched into the rice paddies…  we carried, along with our packs and rifles,   the implicit convictions that… we were  doing something altogether noble and   good. We kept the packs and rifles;  the convictions, we lost.” (Caputo)  US reprisals against locals may result from  anger at casualties, but also frustration at   their inability to hit back at the VC.

 The  State Department’s Daniel Ellsberg joins a   patrol in 1967 which destroys a civilian home: “Their desire to burn the house was in part   the result of frustration and in part  reflected the fact that they honestly   didn’t know what might work.” (Appy 193) South Vietnamese civilians also experience   violence from the Viet Cong.

 The escalation  of the war in 1965 weakens support for the VC,   so they resort to more coercion and  political pressure to get recruits,   supplies, and intelligence. Civilian contact  with US or ARVN troops also results in political   accusations and denunciations. Le Ly Hayslip, a  South Vietnamese villager, is attacked by the Viet   C

ong when her loyalty was doubted. She concludes: “After a while, our fear of the Viet Cong… was   almost as strong as our fear of the  republicans. If the republicans were   like elephants trampling our village, the  Viet Cong were like snakes who came at us   in the night. At least you can see an elephant  coming and get out of the way.” (Langer 198/109) The psychological impact and tactical  reality on the ground mean that by   1967 the war is a stalemate.

 When US  troops engage the enemy on their terms,   they cause high casualties, but the nature  of the fighting is taking its toll. North   Vietnam is also carrying out a strategy of  attrition, and arguably more successfully. But Westmoreland doesn’t think North Vietnam  is winning – in public at least, he emphasizes   progress. By 1967 there are 485,600 US troops in  Vietnam, although Westmoreland wants even more.

Large scale search and destroy operations in early  1967 seem to confirm Westmoreland’s opinions.   The US claims it kills 2,000 enemy insurgents  in Operations Cedar Falls and Junction City,   while Westmoreland states there were fewer  than 242,000 Viet Cong fighters left in the   country. The reality is not so clear cut. MACV’s figures are almost entirely wrong.  

By establishing body counts as the metric  for success, US commanders inflate the   figures – sometimes by double. Officers eager  to show progress or ability post high estimates,   or count civilian dead as Viet Cong  according to a blunt unspoken rule:   “if it’s dead and Vietnamese, it’s VC.

” The focus on quantifiable data means concepts that   aren’t easily quantified, like morale, ideological  support and opinions of locals, are sidelined, in   a “if it can’t be counted, it can’t be important”  mentality. But this attitude ignores vital   elements of warfare, especially counterinsurgency  operations, and applies clumsy numerical values   to complex socio-political issues.

 The US approach is also based on   their estimations of North Vietnamese limits and  capabilities. MACV consistently underestimates   how North Vietnam can sustain high losses through  its conceptualisation of the conflict as a total   people’s war of revolutionary unification. The  CIA, who are critical of the statistical methods,   report as many as 600,000 enemy in  South Vietnam in 1967 with 200,000 North   Vietnamese entering draft age each year.

 Additionally, US bombing has not brought   victory. Although Rolling Thunder destroys 59  percent of power stations and 75 percent of oil   storage in North Vietnam, this has little  impact on a majority agrarian society and   unmechanised military. Bombing is also expensive  and dangerous. More sophisticated anti-aircraft   weapons mean for every dollar of damage  caused by bombing in 1967, the US pays $9.50.

Instead, US bombing and pursuit of the body  count is having a negative impact elsewhere.   Americans are less likely to support  the war and international opinion is   also turning against the US. In Sweden, India,  and Japan, many people are publicly lauding the   North Vietnamese for their resistance.

 In late 1967, Westmoreland and Johnson   embark on a public relations tour of the US  to convince the people of their successes   in Vietnam. Westmoreland tells the public: “The ranks of the Viet Cong are thinning… The   end begins to come into view.” (Appy WCW 166) The first months of 1968 will prove him   disastrously wrong. SPONSORSHIP  The Vietnam War is perhaps the most well-known  “hot” proxy war during the Cold War when the   global super powers were not battling directly  out of fear of nuclear retaliation – even though   they came close to direct confrontation  during the Cuban Missile Crisis just a few  

years before the escalation in Vietnam.  And while the nuclear arsenals expanded,   the Soviet Union also pursued their vision of  Nuclear Powered Communism by rapidly increasing   the production of nuclear reactors. Whole cities  were built to accommodate a new atomic elite that   would help produce limitless energy.
