The US also favoured firepower, but they were not as well served as the germans in the squad based MG and saw the rifle component of the squad as a means of boosting their squad firepower. Hence the thinking that led to the garand. in practice the US squads always missed the benefits of a proper squad MG, and the US whilst advocating a firepower solution to their squad battle solutions, then prompltly nobbled it by failing to make the Mg the main focus of their squad tactics.
I'm assuming that recognition of this led to the fielding of the M1919A6
From M1919 Browning machine gun - Wikipedia, the free encyclopedia
The M1919A6 was an attempt to provide US forces with a more portable light machine gun, similar to the German MG 34 and MG 42 machine guns that they were facing. The M1919A6 had a metal buttstock assembly that clamped to the backplate of the gun, and a front barrel bearing that incorporated both a muzzle booster and a bipod similar to that used on the M1918 Browning Automatic Rifle (BAR). A lighter barrel than that of the M1919A4 was fitted. The M1919A6 was a heavy (32 pounds (15 kg)) and awkward weapon in comparison with the MG34 and MG42 and was eventually replaced in US service by the M60 machine gun in the 1960s.
