Hmm, that reminds me of when we did a bunker call during mortar attacks, if it wasn't a true "run for your life" kinda event (which many were unfortunately), I would have the sense to grab the Nintendo DS pack on the way out the door. It hung on a nail by the shoulder strap right by the doorway, right next to the body armor and the BOB. I'd say about 1 in three events I took the DS to the bunker with me. The battery pack in that thing lasted a good 40 hours between charges. It is too bulky, though, for packing along into the wilderness. Besides, it kinda defeats the point of being out there.
