I use Gunner’s Up stick men. They have units that you can use as standout guns and make a manual reload retired gun. They are very reasonably priced and easy to set up. For the cover I use old long sleeve white “T” shirts. I buy a cheap king size pillow case and sew it into the bottom of the “T” shirt. Add a short piece of 1” PVC pipe in the bottom of the pillow case for weight. This makes very tall and cheap gunner. The arms to the “T” shirt will wave in the wind for a little real action at each station. Mine are at least 10 years old and are in good shape still.
