The M101 is a 155mm artillery canon used by the U.S. military from 2016 and on. It can fire High Explosive, Armor Peircing, Cluster, and illumination. The coordinates are input into the onboard computer. The correct elevation and train. All aiming is done manually. The Army engineers took designs from the M777 and inproved others. The M101 was the finished result
Hey that's pretty cool!
I really know absolutely nothing about artillery but I made one anyways :D
Take a look at this and give me some feedback (since you obviously know a whole lot more about guns then I do.)
