Some who redeploy to Iraq take some of these with them for special occasions.
COMBAT COMPARISON
During the United States Vietnam War of 1965-1972 shotguns played an active role with ground forces and buckshot and flechette ammunition were actively evaluated for combat effectiveness. Combat evaluations from May 1967 to February 1968 were made with flechettes, M162 00 buckshot, and XM257 #4 buckshot. Flechette ammunition indicated a high lethality at all ranges with several one shot kills at engagement ranges to 100 yards, flechettes were prefered by combatants equally to 00 buckshot during this test phase. Flechette ammunition and 00 buckshot were also equally prefered over the issued XM257 #4 buckshot, which proved ineffective under combat conditions, lacking the penitration and terminal performance of either flechettes or 00 buckshot. Adoption of a standardized flechette cartridge was hindered by the United States govenment decision to begin disengaging from the Vietnam War. Flechette superiority to buckshot has proven manifest for all aspects of performance in velocity, grouping, and terminal effects.
