Urban Warfare: "Combat in Cities" 1968 US Army; from Your Army Reports #14, The Big Picture...

In some scenes you can see M14A1. It replaced the BAR as the squad automatic weapon. It had a
full pistol-gripped in-line stock to control recoil, a vented plastic upper forend to save weight, a muzzle compensator, the BAR sling, an M2 bipod, and a folding metal vertical foregrip mounted under the forend of the stock.
