Everyone should have a long, a short, and a melee weapon.
If I had the choice, I'd have all three carry a rifles and/or carbine that use the same ammo and mags for their primary. I prefer the M4/AR platform.
Sidearms would be whatever the person could handle. Anything in 9mm, .40 S&W or .45 ACP since these are the most common calibers for semi-autos.
Melee's are a different story, whatever someone can carry and use.
I would like to update my entry on this forum, I have posted once before but looking back... I don't know what the hell I was thinking.
Primary- Custom AR15 (probably a Bravo Co. with a Noveske Barrel)
Primary- Remington 870 slug gun.
Secondary- Smith and Wesson 629 Stealth Hunter (I know its retarded, I don't care though)
