Okay, I'm not actually in YET, but my husband is an infantry NCM, and all he does is complain that it is REALLY boring on a standard day - you don't do nearly as much as you do in training, and especially now coming up to summer, there isn't much training or anything going on.
That said, he generally has PT sometime between 07:00 and 07:30 (could be a run, time in the gym, or as on some days, didly squat), then has a 10:00 timing for which they may have a class, do some sort of PT-style training (rappelling, hand-to-hand, rock climbing, etc.) Lunnch usually by 11:30ish, then back for 13:00 and again training of some sort, and off some time between 15:00 and 17:00. There are time when they'll head out to do field training, in which none of the timings are relevant, and depending on what's happening elsewhere on base, they may have other specific tasks or possibly nothing to do (after their last EX they spent several days cleaning the LAVs, whereas this week he has had days where they've been released early because of a lack of work, like today.) And at other times, he may be out overnight for field training.
Now, this isn't indicative of all infantry, nor of even every company in the battalion (2RCR). It just happens to be an average day for him. Things change, and honestly, we pretty much believe that no day is really "average" since he can be doing so many different things at so many different times. But I hope it helps a little bit.
