I shot them they pull out a machette and start pacing around and letting me shoot them. Ohh and they might run away too That is why I hate them. You brought up fo3 so lets talk about Enclave. They used cover when getting shot at CL no. Enclave fired back- CL not so much ONLY 1 IN 4 OF THEM HAS A GUN. Im starting a thread about this. I have to know what people think.
Well, they run away because of this simple logic. Why bring a knife to a gun fight? If you take out the man with the only firearm, more than likely they'll scatter. Plus, when you fight the assassin hit squad, they use tactics. You usually will come across a lot of recruits (which are the weakest of their soldiers) while walking around in their territory. Plus, you can kind of look at Caesar's Legion as Native Americans. When American colonists (NCR in this case) started Manifest Destiny they came across a lot of Native Americans (switch Native Americans to tribals for the case of the Khans and other tribes) and basically slaughtered them due to having more technology. Plus, the American colonists pushed the Natives out of their land, and into a reservation, which eventually they would take the reservation away from them, or just give them plan horrible land to live. You can compare that to the case of the Great Khans, where they got slaughtered and pushed back to Red Rock Canyon (horrible land to grow crops and live). So, Caesar's Legion (basically a combination of tribes) can be looked at as a group of soldiers with only a handful using ranged weapons, and a lot using melee weapons, fighting back against the desire of Manifest Destiny of the NCR, and also complete their Roman inspired version of Manifest Destiny (which can be looked at as a combination of a desire to be like the Romans, and also as Native Americans fighting back as not wanting their land taken.)
Don't know a lot about Native Americans, look up http://en.wikipedia.org/wiki/Sitting_Bull or http://en.wikipedia.org/wiki/Battle_of_the_Little_Bighorn. You'll get the drift.
