The movie Child's Play 3
(Justin Whalin, 1991) features a class of Military Academy cadets using "paint bullets" during a training exercise.
Andy (Justin Whalin) is now a teenager, and enrolled in a Military
Academy. The Academy is sending the class out on a 'capture the flag'
The class' commander tells them they will be using the "standard
Springfield ought-three", a classic bolt-action military rifle. He then
their specialty paint ammo against a nearby door.
First the Red Teams', then the Blue. The hits look like actual paintball marks, but were probably not fired from the rifle.
Meanwhile, inside the apparently-unguarded armory, Chucky finds several
racks of color-coded 1903 Springfields, ready for the Cadets.
Chucky takes one down, and unloads the "paint" round.
And drops it on the floor. Note the "bullet" is sticking further out of the shell than when we saw it above.
Chucky then reloads the rifle with a live full metal jacket round.
He goes on to do the same thing with the rest of the Red Teams' rifles.
The "bullets" appear to be a clear plastic or glass case, filled with a
substance. These are not
Simunition rounds; Simunitions use a specialty cartridge case, and have a grooved, translucent projectile.
Note the slight streak of red on the concrete at the left, indicating
one of the 'bullets' may have broken open as Chucky dropped it.
The two teams then head out for their exercise. Very little of the
actual exercise takes place, thanks to Chucky's later actions; only one
Red rifle is
seen being fired (killing some poor cadet) and the Blues are not seen to be fired at all.
