Hey Fluttershy your cuddle buddy Midnight Phoenix here to answer your question what you saw is called an RPG short for Rocket Propelled Grenade, the model you saw is called the RPG-7 and is used by infantry soldiers to take out armored fighting vehicles when they don't have artillery or a tank available to them. Oh and Firefox I hope you don't mind another channel I follow I asked them if they could use my design from your channel because apparently I know a lot about MLP FIM.
