Yes it is. More like two years ago. At least it's the long version of the Apache Video.
The guys probably weren't setting up an IED, but rather transferring something like an RPG or ManPad SAM. One of the guys is shown trying to get it into action just as the gunner shifts targets from another guy to him. He never gets it, or anything else, into action, ever again.
Zactly. They were dropping off a weapon so they could pick it up later.
