I mean there are maps from when the Mongols ruled Large chucks of what is now Russia, so does that mean Russia should give the land back to Mongolia? Point is things change and comments like that serve no purpose at all and just just stupid
But if you listen to the west the lines currently on maps are set in stone and cannot be moved... unless it is in their interests and then it is OK to move them and create new countries etc etc.
All of which don't want to get exposed to toxic fumes.
Who said it is toxic?
On a battlefield you will have the air filled with burned powders from rifles and other weapons of all types and things burning giving off smoke and fumes... even the soldiers themselves will operate under the cover of smoke screens...
Maybe there is an operating mode where you can keep the hatch shut in high risk areas and just drop the primer cap on the floor instead.
The timing needed to drop a grenade into that small hatch that ejects stub metal shell cases would need to be world class... it does not remain open for long and is rather small.
That extraction hatch opens automatically and closes in a sec. Drones are no issue, unless the Ukrainians drone operators are clairvoyant and genius-level physicists, as they'd have to foresee the gun firing and time the drop with the drone's current height, the fall speed of the munition etc in mind.
Plus, as you could see on the video the shell stub is not ejected when the round is fired... it is ejected when the next round is loaded... which might be just after a shot is fired or it might not...
Those drones with a higher weapons load look like they are in service. It's raining grenades on these hohols heads
Clever... use a drone dropped grenade to make them scatter and then shower the area with grenade launcher rounds a couple of times to get some hits...
You get smoke, the hatch has to stay open and some Ukrainian $1000 drone drops a grenade into your hatch.
Wrong... they likely had the hatches open to improve visibility for the cameras by making the tank interior brighter and easier to see... normally in operational use the hatches would be closed so the smoke would not enter the turret so much because the air pressure in the turret would be higher as the air is coming in via the ventilation system... which has filters on it... for the same reason that in an NBC conflict the hatches would remain shut and the air filtered to prevent chem or bio weapons or radiation from the outside entering the tank...
On the Abrams they have chosen to just drop on to the turret floor; not ideal either to sit in between spent primer caps stacking up on the floor.
A human loader can aim the empty case at an empty gap on the floor or perhaps even put it in an empty storage space for ammo... it will be hot when it first comes out but that is why he will be wearing gloves...
The full length brass case also seals the fumes and reduces the amount of fumes coming into the crew compartment.
The main reason the 2A72 was developed was because the 2A42 filled the BMP-2 turret with fumes when fired at the highest rate of 500rpm.
Hardly the end of the world... just fire at the lower rate.
