I think they might be learning the "sight picture" they should see when they shoot at a towed target in the air. I think the cloth at the top of the pole represents the tow target and the little ball on the stick is where they are suppose to aim. They are learning the "offset" or lead distance to the tow target they should see in their ring site when they are actually shooting in the air. They can't be firing the guns as the little wooden stands would fall over from the recoil. The guns may not even be real, just mock-ups. Notice also the ring and the bead seem to be "reversed" on the guns.

Possible , thank you .

Perhaps the cloth is a windsack that provide some motion to the target in the wind. Giving the gunners a more moving target in stead of a stationairy one.
