brutethe brute duhIt all depends. A Brute Chieftain could kill a squad of four average grunts in one shot with a gravity hammer no sweat. A normal Brute minor would probably become overwhelmed and fall to plasma grenades, probably killing at least one or two of the grunts. 4 spec ops grunts with fuel rod guns could kill almost any normal brute, but perhaps not a chieftain due to his invincibility power-up. One thing to take into consideration is that grunts almost invariably flee when they lack strong leadership, and their disorganized panic would give the enraged brute an advantage.
