“YIKES!!! Good thing it was a dummy round!
Like the scene from “Stripes” Where John Laroquette (the idiot commanding officer) demands that a recruit “fire the mortar, soldier” when it hadn’t been set up. Warren Oates (the DI who has just scaled a rope climbing platform) hollers out “incoming!” True to the script the mortar round hit the platform.
