Eat your heart out!
This little sucker will take out a school bus at 11 miles.
It delivers a 200 lb. high explosive projectile.
Damn, it was fun!
It is an 8 inch, towed howitzer. It went into service during WWII and was used into the 60's. You pull it with a 10 ton prime mover truck, has a crew of eight (which you don't need. It can be shot with about four people.) It will deliver one round per minute.
You need to swab out the "chamber" with a wet mop after each round is fired in order to extinguish any burning powder fragments. If not...you are in for a surprise when you load the charge.
