Using tracer rounds at night on targets placed on a hillside, is insanely stupid. Unless people like forest fires...leave tracers for the military. They are banned in Bisley Camp due to fires, and thats a permenant year round shooting range, not a ad-hoc mountain side with some targets on it.
Tracer rounds may be a fire hazard but im pretty sure the "50-gallon drums filled with gasoline and strapped with sticks of dynamite" could cause a little fire as well.
...heavy machine gunners load their weapons with phosphorus tracer rounds and take aim through night vision goggles at glow sticks marking 50-gallon drums filled with gasoline and strapped with sticks of dynamite.
Looks like wicked fun, im sure you could easily overspend there.
