Do you ever notice that the military is always trying to reinvent the wheel?
The got rid of the large caliber weapons because they weighed to much.Now they are changing course.
“The military” huh? Guess you didn’t grace a uniform at any point, did you?
Our job is kill people and we need better tools. The “mouse gun” doesn’t work well in the longer distance fight and doesn’t penetrate cover well.
Tough to understand?
True. But the military doesn’t change small arms and basic infantry weapons very often. This is true for most countries.
