Well, a micro-video, actually. There is a high definition version at YouTube, if that helps.
The level of detail doesn't disappoint. Like the Churchill AVRE's main gun needing some extra time to re-load (the charge is quite heavy). I also liked how the Crab turns the turret to protect the main gun, rendering it devoid of firepower during the breaching ...
