Re: Drag bag
As VC said, drag bags are currently issued at sniper school. However the M1950 weapons case with Mods is a great drag bag, Felt pad for carpet makes a great liner. Ensure there are pockets big enough to easily remove a set of issue bino's, and a pocket for accessories such as a saw, pruning shears rubber bands or hair ties and netting. Would highly suggest a cylindrical pocket for a Camera tripod as well. As you can see the time spent at a machine adds up quick but quality worksmanship is a must, these things take a beating and easy access is a must when the eyes are looking for you, cant be flopping around trying to get items out of a bag. I would suggest using the issued bag, then when you have figured out what works, and where... building the "perfect" drag bag for yourself.
If you are still going in April I would suggest looking at buying a high quality Camera Tripod such as a Manfroto. There is nothing worse than taking a shot a watching a tripod break, creating all sorts of movement, losing your loophole, only to achive a "No Go" or get busted. If its not you... pretty funny, if its you, you'll curse yourself for not spending the $175.
I guess what I'm trying to say is wait on the drag bag, spend your time sewing on your ghille, get someone WHO KNOWS show you how to get into a loophole, rucking, and studying.
