The Browning Automatic Rifle was initially developed during World War I, when the United States entered the conflict with an inadequately small and obsolete assortment of various domestic and foreign machine gun designs. Although it arrived late in the conflict, the BAR made an impact disproportionate to its numbers; it was extensively used during the Meuse-Argonne Offensive and made a significant impression on the Allies (France alone requested 19,000 automatic rifles to replace their notoriously unreliable Chauchat machine rifle).
Durring WW2, the rifle was more battle effective than submachine guns. Most allied armies had 1 BAR for every 12 men. 1 man would have a sniper rifle while the rest would have rifles.
