I can't really think of much TA50. I was issued pretty much everything I needed. I got some mag pouches for my armor that are a lot better than using the LBE, but recently we were all issued new ones so we are all the same. Woodland camo of all things too.
hinking.gifAs far as your weapon, depending if you know what you will be doing, and if you're using a 16 or M4, get a mag pouch for the stock. The only ones we could get over here at first were cheap ones that weren't built very good. I bought mine before I came over and got a good one. 3point slings are pretty useful too. My unit got us some.
A scope, bipod, tac-light might be useful too. I brought a 1.5-5 leupold for my A2, and an accesory rail that bolts onto my handguard for my M6 laser/ light combo. Also a mag clip to attach 2 of them side by side so the first reload is quick. I haven't really needed all that yet, but I'd rather have it and not need it than need it and not have it.
Last time I was here in 03 though I had a 3-9 Simmons and had the crosshairs on people several times while on guard duty in the top of our building making sure they pulled a gas can out of their trunk and not an RPG.
As far as clothes. The 'under armor' shirts at the clothing sales work pretty good in the heat. At $20 a shirt though they get expensive. A couple people I know bought 1 or 2 and ended up buying one for everyday of the week.
I can't think of much off the top of my head at the moment except to recomend water-proof camera/laptop cases because the talcum-powder like dust will work it's way over time through zippers. And throw some cans of compressed air into your footlockers. They work good for laptops and weapons (as long as there's no oil on the bolt). That Miltec seems to work pretty decent
