1. WWII, first war in history in which every US fighting man was armed with a semi-automatic rifle, the M1 Garand. WWII created the AIRBORNE divisions (paratroopers).

2. Vietnam, first war in history in which every US fighting man was armed with a fully-automatic rifle, the M16 Jungle Rifle (assault rifle). Vietnam War created the AIRMOBILE divisions (helicopters).

Note: Secretary of Defense McNamara "clarified the M16" for jungle warfare only.
