The Patrol - S1-E8
Visible crew/equipment: When The Patrol is on its way, one of the boats tilts over and some soldiers are screaming they can't swim. At some point during that scene there is a wide shot with in the background the other side and a skylight. Right in the middle of that shot on the other side you can see a man walking away wearing a orange vest or jacket of some sorts. Might be the pyro-guy. (00:33:15)
Replacements - S1-E4
Visible crew/equipment: Just after the jump into Holland, the paratroopers run across an open field. Just before the camera cuts to them in a ditch, there is a wide shot of them running in the field. At the end of the field, two large blue tents can be seen.
Replacements - S1-E4
Visible crew/equipment: When the damaged Sherman is from behind rolling forwards, two crew members can be seen guiding it in white T-shirts through the hedgerow. (00:33:20)
Replacements - S1-E4
Visible crew/equipment: At the end, as they are moving out there is a high shot of two trucks driving towards the camera. The first truck reflects the camera shadow on the ground. (00:52:20)
Day of Days - S1-E2
Visible crew/equipment: Early on the camera pans from outside the aircraft into the jump door and looks at the men. When the camera moves in a shadow moves over the guy sat by the door. (00:06:20)
Answer: That actually is the clip. It is loaded into the top of the rifle, and is ejected with the last round. See http://www.wwiitech.net/main/usa/weapons/m1/.
