My BIL just got back from Afghanistan. As stated, soldiers are able to get almost all thier needs met in the field at this point. So it falls back on homey items like snack foods, entertainment, and the like.
My BIL had a work laptop he was able to skype from. If our grandparents could see that! My Grandfather was a POW in WWII and all my Great Grandmother got was a yellow telegram!
Anyways, I sent him alot of geedunk. Sorry, junk food
. Chips, candy, gum, jerky, and the like. Sent him batteries a few times. He asked me specifically for a flashlight, so I sent him an LED mini mag and an LED headlamp. Sent him a cheap pocket folder as a backup knife. A few books and magazines. Maxim and FHM were big hits. I even sent him some of my old magazines (cycling, boating, fishing), which he just left in common areas to share with others.
Before he left he told me he wasn't being issued a drop leg holster, which would make accessing his M9 easier in body armor. Bought one for him.
