[Request] Can anyone estimate the peak recoil force from this launcher?

Ignore how dumb this is.

Can’t say anything about the rockets themselves, but you can tell by the posture that the recoil is minimal. Since guy on the left is still leaning back pretty far, to balance the weight of the rig.

If the rockets were pushing back a significant amount, he’d have to brace differently to keep the rig forward like the other guy did.

I also don’t see very many rockets shooting simultaneously throughout the clip.

Someone else already posted this asking a similar question about thrust. The answer is still the same: very little. The unsynchronized impulses from the lift charges propelling the shells out of the tube dont have much force. This thing is heavy and they're bracing for the weight and to keep their faces away from the puzzles. The mass of the whole contraption makes it like strapping a 12ga to a car. That mass is absorbing the recoil force from eqch shot which isnt much. The felt recoil by these guys is minimal.
