US Infantrymen (grunts) carried either a rifle (M-16), or a machine gun (M-60, belt fed), or an M-79 grenade launcher. If the grunt was a radio operator (RTO-Radio Telephone Operator) he also carried a radio ON HIS BACK.
Medics, (whom may or may not have been authorized to carry arms, usually carried an M-16 or a .45 pistol).
Straight leg infantry (grunts) were issued back packs (RUCK sacks) with round edged aluminum frames. Airmobile and Airborne grunts could be issued those packs too. Mechanized Infantrymen were not issued RUCK sacks or bayonets, if they were; they were turned in later in the war.
All straight leg grunts carried an average of about 6 (1 qt) green plastic canteens attached to their rucks and at least 1 metal canteen cup which was used for either heating food or water. Straight leggers also carried 3 to 6 or more hand grenades and a maybe a bayonet. Plus 100 or 200 rounds of machinegun ammo, and two to four bandoliers of M-16 ammo (seven M-16 magazine pockets to the bandolier, each magazine normally loaded with only 18 rounds of 5.56mm; capacity was 20 rounds, but to preserve the magazine’s spring it was compressed with only18 rounds). All of these items were carried in the extreme humidity, thru knee deep mud, and up jungle strewn hill tops. Continue reading
