In addition this was the only USA defense that did not require a continuous power supply, however it was still vulnerable to EMP weapons or a Microwave tank. If garrisoned by a Pathfinder or Rangers, Fire Bases could provide US bases with the effective anti-infantry defense they were otherwise lacking. Fire Bases worked best in tandem with Patriot Missile System. While the howitzer itself was not powerful enough to sufficiently destroy incoming armoured vehicles by itself, garrisoned infantrymen, usually composed of Missile Defenders - would often be more than able to finish the job.
