Alright, MovieMonsterguy, I am declaring this battle unfair.

Why?

First of all, dinosaurs do not have bulletproof skin, so your "skin is pretty thick" argument (which is pretty shaky to begin with, consdering you gave no exact measurement, just a generalization) holds no ground here. A Heckler & Kock G36C rifle fires the standard-issue 5.56 mm NATO round, which can be fired at speeds of up to 3,018 feet/second. Assuming (now, I'm just humoring you here, and this is assuming) that the dinosaur's skin was indeed thick enough to stop a bullet flying at those speeds, the impact on the dino's flesh and bone would likely have a severely traumatic effect - internal bleeding, broken bones, and the like would probably ensue. Even the Mini Uzi's comparatively smaller and slower 9mm round traveling at around 1,312 feet/second would still poke a lot of holes in a dinosaur. AND this is all at ranges of at least 150 feet or more.

Now the Allosaurus's top running speed was between 19 and 34 miles per hour (according to its Wikipedia page) and the average of those 2 numbers is 26.5 - so let's assume (again, this is incorrect, but I'll humor you) that the dinosaurs never tire out and can maintain that constant speed even with grievous injuries and fatigue. That's still only 38.8 feet per second, which means that if the Massachusetts Regiment Militia opens fire on the dinosaurs at the maximum firing range of their assault rifle - 800 m or 2,624 feet, they will have 67 seconds to keep firing at the dinosaurs before the Allosaurus will reach the humans. That's over a minute of concentrated fire - and it'll only get more accurate the closer the dinosaurs get.

Then, finally, we analyze the RPG here. That has a lethal blast radius of around 23 feet - so it's probably going to have debilitating effects at slightly longer ranges in every direction around where that warhead blows up. That's gonna fry the dinosaurs right where they are - or at least stun them, freak them the hell out, or send shrapnel flying into their bodies, injuring them. One warhead is all the humans need.

And of course there's human strategy and intelligence, as well as training and combat experience, vs. dinosaur brains.

8 humans vs. 2 dinos is unfair - that gives the dinosaurs 4 humans each to have to take down, while the humans by comparison need (theoretically) half of a dinosaur to kill. And the humans are armed to the teeth - it's ridiculous. They don't even need to reload - they can just drop one rifle, pick up another, and then go to their SMG or shotgun or whatever when that magazine runs empty. Heck - one human vs. 2 dinos is sketchy enough as it is, but this battle is flat out unfair. And don't you even try to tell me otherwise.
