As my understanding is, homosexuals still have to register for the selective service. It seems logically, they should be exempt if they're ineligible for service. Then comes the question about young men faking homosexuality to avoid the draft, if that should happen.
No one has used shelter halves in years. I turned mine in because I knew I would never use that piece of crap and it's one less piece of gear to keep up with. I use my poncho and bungee cords or a 8 x 10 foot woodland tarp. It is big enough for two soldiers and all their gear and it's a lot more waterproof.
