The P2-120 HE is a primary weapon available to the Prowler. The P2-120 HE is the Prowler's specialized anti-infantry weapon, firing high explosive rounds with a greater and more lethal blast radius than those fired by the other two cannons, however lacks in anti-tank damage. As it is geared towards anti-infantry warfare, it is definitely more favourable to take the P2-120 HE when an infantry fight is guaranteed, however it is not the end of the world if the P2-120 HE is pitted versus enemy armor, as it still does a fair amount of damage.
