A 2-minute video on how to operate the DeepFire AT4 replica was made by Fung Li. It is a good step-by-step instruction that ends with a vehicle exploding when the fire button was depressed all for good effect though this one is just for airsoft and you can't destroy vehicles with it. But if you still find the instructions too tedious for your simple brain, you can still use the AT4 for photo-ops as you will look good with it.

Watch and learn (and enjoy too!):
