Vietcong Dill Camp 3 Problems

[mfw41]

I'm playing the VIETCONG TUTORIAL(the DRILL CAMPS). In DRILL CAMP 3(the one for HEAVY WEAPON TRAINING GRENADES and such) and I dicovered a glitch. In the first two sessions there were were PAPER TARGETS to SHOT at, in the third session where you get to use the grenade launcher there were NO PAPER TARGETS to DESTROY. Did anybody have PAPER TARGETS to shoot in the section?
