3 combat deployments, 2 to afghanistan, 1 to iraq.

never had any issues with any of my issued weapons systems, from my pistol to heavy machine guns.

All operated as designed, functioned properly when required, and if someone actually pays attention to their weapons system, they'll do fine regardless of the caliber. Shot placement is paramount to a round doing what you want.

Cleaning a star chamber is easy, especially if you have a star chamber cleaner. We had 1 per squad in the squad cleaning kit. Earplug in the muzzle and close YOUR DUST COVER.

Oh yeah, all those deployments were during my 6 year stint in 3rd Ranger BN.

Bayonets are great, but if you have a LMG, or a M203 you're out of luck.. and we had 1 M249 and 2 M203's per fire team.
