The fire from the air was definitely from a rotary winged aircraft. If it was Mosul it was probably Army, and therefore probably either an AH-64 or OH-58. I'm not too sure about the ground fire, but I would guess 25mm fire from a Bradley. But this video gives some idea of why some types of fighting (like Close Air Support) is now easier at night than it is in day. Laser markers and spotlights work wonders to pinpoint a target, and picking out targets from natural backgrounds is much easier using Infra-red than your eyeballs.

Interesting. I wonder if they could develop some AI binoculors to aid soldiers in picking out dyatime targets.
