Help with identifying German uniforms

Greetings from a new member in Georgia, USA.

The attached photo shows two individuals in German uniforms standing on the wing of a B-17G that was shot down over northern Holland on 14 February, 1945. The aircraft received direct flak hits resulting in a massive fire in the midsection. Some of the crew bailed out but the pilot and copilot were trapped in the cockpit. At the last second the copilot managed to maneuver the aircraft into a crash-landing near the village of Wormerveer. The B-17 broke in two upon hitting the ground (the tail section can be seen in the background). The life raft compartment is open because the raft was used as a sled to drag some wounded crewmembers to the nearby village.

It's a grainy photo, so there aren't many clues except the boots, trench coat, garrison caps, and trousers. Are either of the two men officers, or is there a way to speculate on rank? Are they antiaircraft personnel (Luftwaffe) or army?

Any insights will be greatly appreciated. Thanks in advance!
