The UH-1 Huey has been used by the U.S. military for decades.
For your viewing pleasure, check out these photos of the restored aircraft on the flight deck of the Midway Museum.
The Midway has their Huey configured as a gunship.
In such configuration, it was armed with two pods of two 7.62 mm miniguns (in other words equivalent to a .308), two M-60 door guns, and two pods of 2.5 inch rockets, with seven rockets in each pod.
Door gunner positions above with what appears to be reproduction of either a .50 machine gun or perhaps .30. I’m a bit fuzzy on machine guns. Sure doesn’t look like an M-60 to me. I’ll make a guess that lots of units reconfigured with .30 or .50.
The Huey was a workhorse during the Vietnam war for med-evac, carrying troops into battle, providing support as a gunship, or as observation platform.
It was used for security, cable inspection, and transport of security teams when I was on active duty in the U.S. Air Force. Occasionally used to transport missile crews to and from the field.
