I don't know if that would catch on. After shooting a shooter should focus on getting everything back in order
I'm with Sarge on that one...
I think that the ro should be aware if what's going on and then after all has been reset...say, hey you in the green shirt, please go and check that target for tape...obviously pick the farthest one. Then when he comes back and says, no, it's taped. Oh, ok..thank you for your help
If he does it on the next stage...repeat until he gets the picture
