This whole 100 men vs 1 Gorilla debate just shows how severely we've begun to underestimate ourselves as humans. It's ONE HUNDRED MEN. What are we talking about???
If 100 men coordinate their attack, 20-30 distract, another 50 swarm it and try to immobilise it (use body weight, go for its limbs) then the last 20-30 go for the kill, attacking its eyes and neck (choke it out). They're winning cmon. Mind you like 20-30 probably don't make it.
