You need to increase the numbers by every round, I was hoping it would be filmed, too.
But, I'll trust your word.
I tried two things. First: 5 Enclave soldiers VS. 15 BOS Troops in an empty field. . The Enclave won with one badly wounded soldier left, and they crouched and moved around carefully, taking accurate shots.
The BOS on the other hand simply stood their taking wild shots, missing alot.
2nd: 5 Enclave VS. 15 BOS with the Enclave behind a couple of of barricades. The Enclave won by using the cover effectively and once again talking accurate shots. There were two soldiers left, one who had minor damage and one near death.
The BOS tried charging them head on, having their shots either missing or hitting the cover.
I did this with no mods on except a couple spawning mods.
Also, sorry for not capturing it on video. Fraps kept shutting off for some reason.
