The guy holding the tube is adjusting sideways and pulling the trigger, the other guy adjust for length.
Mortars have a bubble levels on them, which have to be leveled for the rounds to hit it's taget, that's why the Marine says "In. Hit it"
In the following video, a Marine mortarman is engaging some Talibs with a 60mm mortar in the handheld, trigger actuated mode. He's aiming the tube, while a second marine is repeatedly slapping what I assume is the trigger.
Is that supposed to increase accuracy or is it because the trigger is unusually awkward to operate or is it something else?

That's how you di it. I've never operated a 60 tho, just 80s and 120s. Not bad for an FO!
I know the 60mm, but I imagine the USMC one is a lot more modern then ours... THe only time ours have anything to do with bubbles is when they are in the bipod role with a C2 sight attached. In the light role it is all about charge setting and bracketing.
