Hey Man - Firstly, thanks so much for your service in Afghanistan. I'm not sure what country you represent, but thank you.
To your program - I think you're doing too much, to be honest - too many exercises. Deadlifts will take care of your calves and core - so take out the calf raises and crunches. Any type of bench work will take care of your triceps - so take out the skull crushers. The pulldowns/rows will hit your biceps, so take out the curls. I'd alternate rows and pulldowns so as not to overtax your back.
If you really want to do iso work, do it with different rep/set ranges than you do for the vanilla HST model, but do so mindful of the potential impact on your core lifts and overall recovery between workouts.
Good luck with your training.
"Determination, Perseverance, Resolution, RESURRECTION!"
