The US Army made extensive use of the bazooka against infantry in the ETO, if you count fighting positions manned by infantry as “against infantry.” Together with the rifle grenade the bazooka gave rifleman a way of attacking hardened positions (whether it be log or concrete bunkers, sandbag emplacements, fighting positions within houses including basement, first floor, and upper floor windows) at range with an explosive munition, which apart from its tendency to wound or kill multiple occupants of the position had the added bonus of potentially demolishing it.

As American forces advanced across France and Belgium and into Germany they were confronted by several types of warfare they had not yet experienced- attacking heavy fortifications, fighting in dense woods, urban combat, and fighting against fortified villages over terrain favorable to armor. The bazooka played a key role in each of these scenarios, because each demanded the adoption of assault team tactics to varying degrees. In general, when faced with these scenarios American formations in the ETO split their rifle companies into assault and support teams, each comprised by anywhere from 10-20 men. The duty of the assault team was to, as the name implies, conduct an assault on the position specified, while the support team covered them by fire, watched the flanks of the attack, and stood ready to repel any counterattacks by the enemy. The standard assault team armament consisted of multiple Browning Automatic Rifles, bazooka(s), flamethrower(s), and demolitions equipment, while the support team boasted BAR’s and light machine guns. In attacking static fortifications the bazooka was used to attack the enemy through firing at the apertures and to blow the rear doors of pillboxes in, after which the bunker would be cleared using standard fragmentation grenades. This role was essentially identical to that which it played in attacking through dense woods- most of the woodland combat experienced by American units in the 1944 campaign held both concrete pillboxes and log emplacements, the latter of which could be suppressed or destroyed by bazooka rounds. In attacking towns and cities it was a handy weapon for engaging fighting positions located in houses, and found a second role as a breaching device. American troops quickly realized that the deadliest place to be in a city or town was in the street, so they began moving house to house by blowing holes in the walls. This process began in an alley or on a secured street, where a tank or engineer team blew a hole in the wall of a house. The assault team then entered and cleared the house before forming up to blow a hole in the party wall joining the cleared house with the next one in the row. With the assault team waiting in adjacent rooms a demolition team or bazooka man blew a hole in the party wall, which usually had the effect of killing the occupants of the room on the other side and stunning or surprising the defenders. Once the hole was created the assault team attacked into the neighboring building with grenades, cleared it, and then repeated the process.
