The Roles and Weapons with the Squad

[Rifleman]

.....suppressive fire will not deter competent troops to any great extent.

Or troops with a sense of purpose and calling, I guess. Sgt. York is the example that comes to mind. A man with a five shot bolt action rifle and a M1911 against several machine gun crews was not deterred.

.....weapons and cartridge supplied to the Viet Namese and initially tested by the 82d Abn Div were not the identical to the weapon the Army later fielded as the M-16.

Was the weapon and cartridge first used by SF in the early days of Vietnam different from those fielded by the Army in 1965? I've read accounts saying that SF really liked the AR-15 when it first came out in the early '60s (War Story by Jim Morris and The New Legions by Donald Duncan).
