A few other factors faced by ATGW/Bazooka/LAW/bunker buster teams
Infantry ATG weapons would need to be capable of destroying enemy armor as well as other targets, they also would be carrying responsibilities for "bunker busting"- reducing hardened targets and creating entry points in buildings. They would
need sensors and communications to allow them to detect and engage targets and work with the rest of the combined arms team.
This would require a crew-served weapon and would mean carrying sufficient rounds (6-10) in order to sustain the battle. Even with only a few rounds, the team would need some kind of vehicle to carry their ammunition, sensors and communications, or they would quickly become exhausted. The ATGW team would also need to cross rough, broken terrain under fire in order to move around the battlefield. Thus the vehicle carrying their weapon would need all-terrain capability. In approaching or engaging in battle, they would need protection from enemy.
artillery and mortars for without such protection, they would not last long. They would also need sufficient protection to
expose themselves to fire while scanning to acquire targets. So, to make infantry bunker-busters a viable replacement for tanks would require a heavy weapon able to penetrate buildings and destroy strongpoints, served by a crew of two
or three, mounted in a high-mobility vehicle with protection against enemy fire and with sensors to acquire targets. ATGW teams need a protected, mobile weapon system to be able to conduct close combat.
This brings to mounted and dis-mounted ATGW teams.
