There is one weapon that I myself could never have the heart to design. A weapon that our Airforce, sadly, is trying to develope. Although it's still not even in the embryonic stage. An antimatter bomb. It is believed that if you fill a bomb the size of a grenade with antimatter, it could destroy an entire nation.

What ever happened to melee attachments on weapons? The bayonet was a good melee weapon, it actually stopped most in their tracks(when bullets didn't). Why is it barely used anymore?

You know how they say there are some metals that cant be magnetised? I believe they can, by changing the electromagnetic frequency. This could lead to bullutproof armor shielding that uses this change in frequency to repel bullets, RPG's, and other projectiles. Imagine the possibilities...fascinating!
