Have you ever seen a bazooka ricochet. Enlarge and watch carefully.

Not common, the ability of any rocket launcher to ricochet is well documented. This is why serious military training uses a target that will engage the fuse to the shaped charge whenever they practice, even when using inert ammo. The damage to the automobile indicates that the round fired from that M 79 Light Anti-Armor Weapon (AKA LAAW) was inert.
Thanks, marine. I was wondering about that.
