“The venerable M113 series can be a platform for many excellent weapons systems, including Dual 50 cal machine guns and Vulcan 20MM cannon, 4000-6000 rounds a minute with a range over 1000 meters. This configuration would slow unauthorized crossings of even the most determined ILLEGAL ALIEN INVADER.”
Take the old M45 quad .50 “meatchopper” and swap out the Ma Deuces for GAU-19A .50 Gatling guns.
Then there is good ol’ napalm😁
I like the way you think :)
