Sledge SMASH!! and I need to learn to shoot!

A little clip from Rainbow 6 : Siege.
I was running as "Sledge" and was working my way into room when an enemy player walks right past me. Once I realized who he was I shotgun him and drop him, then I missed him with a few shots while he was on the ground I finally walk up and knock him out of his misery...luckily he couldn't shoot while down, cause apparently I can't hit the slow moving targets!
Thanks for checking out my video!
