Per their use in MREs, yeah, nicotine is a really good drug to have when you're likely to be in combat in the next four or so hours. It drives blood to the core and away from the periphery, it heightens alertness, it increases testosterone, and there are a lot of other effects.
Like all drugs, there are bad parts and good parts to it. Since most people are hopefully never going to be shot, it's positive effects are mostly useless and the long term negative effects will kill you. But if you have a reasonable suspicion that you are going to be in mortal danger soon, yeah, I'd have a cigarette.
