WWII cannons could use a brake

What is that odd-shaped thing on the end of the barrel of the FHC’s 17-pounder (and many other WWII cannons)? It’s not a flash suppressor, it’s a muzzle brake. These slots, vents, hole, or baffles redirect propellant gasses sideways, allowing for a simpler, less hefty recoil system in the gun. The brake also helps keep the weapon accurately pointed at the target, should a second round be needed to finish the job. You’ll notice that most modern tank cannons no longer have a muzzle brake (but some artillery still does). This is because the newer tank’s recoil systems are better engineered and can more easily deal with the shock of firing.
