/ref> Ultimately, many British officials came to the conclusion that their S&D tactics were working poorly. Troops assigned to S&D missions would often use heavy-handed tactics on individuals and settlements suspected of supporting the MNLA, alienating the local population. MNLA insurgents held numerous advantages over their British opponents, including residing in closer proximity to the countryside's population and having familial relations or close friendships among local villagers. While MNLA insurgents rarely directly engaged British forces, they frequently targeted civilians to elicit material support. Patrols in the jungle, a common part of British S&D operations, were unpopular with the troops due to having to spend significant periods of time navigating unfamiliar terrain filled with dangerous animals and insects while concomitantly watching out for MNLA ambushes. British forces, unable to distinguish friend from foe, had to adjust to the constant risk of an insurgent attack. These fears led to incidents such as the Batang Kali massacre, in which 24 unarmed villagers were killed by soldiers of the

In his three-phase strategy, the first was to tie down the Viet Cong, the second phase was to resume the offensive and destroy the enemy, and the third phase was to restore the area under South Vietnamese government control. Most "Zippo" missions (so named for the Zippo lighters used to set fire to villages believed to be aligned with the Viet Cong) were assigned to the second phase around 1966 and 1967, along with clear-and-secure operations.

The offensive failed to destroy the NLF's headquarters or to capture any high-ranking officers and so it had little effect toward Hanoi's plan.

's Tet offensive in 1968. As the war grew more aggressive, so did the missions, and search-and-destroy and clear-and-secure operations became merged. Search-and-destroy missions had many flaws. First, there was lack of distinction between clearing and search-and-destroy missions. Thus, clearing missions, which were less aggressive, eventually morphed into a more violent and brutal form of tactic, just as search-and-destroy missions were. With the lack of distinction between clearing, and search-and-destroy missions, pacification was not pushed. Such a response led to the Mỹ Lai massacre of 1968, where American troops massacred at least 347 Vietnamese civilians. Guenter Lewy, a professor of

, argued that the generals and war planners severely underestimated the enemy's abilities to match and even to exceed US forces. Large numbers of Viet Cong troops would be killed or captured, but they were quickly replaced. Enemy forces were initially pushed out of certain territories, but as soon as the American forces left the areas, they simply returned with more reinforcements and weapons. The effectiveness of the missions is also doubtful. In one of the first search-and-destroy missions northwest of Dầu Tiếng, named Operation Attleboro, a US report states that 115 U.S. soldiers were killed, and the North Vietnamese lost 1,062. In Operation Junction City, the report also states that 282 US soldiers were killed, and the Viet Cong lost 1,728 guerrillas. Those estimated figures, however, should be considered in light of how they were obtained. They were almost exclusively gathered by indirect means: sensor readings, sightings of secondary explosions, reports of defectors or prisoners of war, and inference or
