Been watching some war movies, and wondering how did the tank crews get rid of the spent shell casing?

I never gave it much thought, but … if they had room to pack them in, then they could surely pack them out just as well if they wanted to.

But I can’t imagine it was so bad. Since they had to stop to refuel fairly often, they could also restock their ammunition at the same time. I would not have expected a battle tank of WWII vintage (since I’m thinking from Fury myself here) would have been expected to pack thousands of rounds. They just didn’t shoot that much. Tank engagements were generally pretty short, I think.

There is a shielded port/tube that the main gun empties are ejected out of by the loader. There isn’t much room in a tank so you couldn’t have those hot spent casings laying about.
The machine guns use what is called a disintegrating belt that falls apart as the gun is fired. Each section of the belt hold one round and connects to the other rounds like a jig-saw puzzle. Where this disintegrated belt goes is probably the same place as the empty bullet casings: out a discharge chute.

@kritiper Thanks I thought there had to be something.

A couple of things I found at Google Books.

Panther
‘When the gun fired, it ejected the spent casing back against a deflector plate that dropped it into a bin below. The bin automatically opened and shut to prevent fumes from filling the turret.’

Here’s a photo of a Tiger model showing a bin to catch the spent casings.

Sherman
’[The loader’s] only “hatch” was a small “pistol port” side door roughly eight-by-eight inches square, which he used to eject the spent shell casings from the main gun.’

Here’s another site with a photo of the Sherman port outlined in red, which also says, “in April 1943 the Ordnance Department decided to eliminate the pistol port as they considered it a ballistic hazard.”.

These ports on newer tanks have to be sealed to prevent any lethal gas (nerve, blood, or skin agents) from entering the tank.
