They have coffee and soda in the mess hall when you get your meals. In the field when eating MRE's they have instant coffee packets in them. Sure it's not like popping some pills or pre workout, but it is enough. Truth be told, in basic you have enough going on that it isn't really a top priority. I'm big on caffeine and I've never really had a problem. If you get commissioned life is a bit easier in a lot of those comfort aspects as opposed to enlisted.
As far as army (infantry) goes, there is none of that. The coffee is contraband and there is no soda. You get powerade.
