Infantry are very versatile out on the battlefield. They can go through most forms of terrain, search buildings, hold ground, and be armed with many different weapons in order to take on a variety of enemy formations. When enemy vehicles bear down, it’s time for the heavy weapons crews to step up and protect the rest of the platoon.
