I personally am glad there is at least one tank round that boils down to "Just hit the thing really good with a durable object". It's a classic you know? The most classic of them all. Also, subscriber gained, keep up the great work!
We had different flavors of the 90mm round to use in vietnam. The Heat round was never used . always the shotgun or HE High explosives. The indrect guns had canister 155mm/ 8"/ 175mm on troops in the open. 10th calvery 4th div.
In US only HE-mpat (any targets from infantry to armor and buildings), APFSDS (pure antiarmor vs MBTs) and rarely Cannister shot (120-mm shotgun shell) being used. No HESH! It's better to have more versatile rounds available than to carry a load of single-purposed ones.
Hey hey, you forgot the OR rounds hero! Which is MPAT with an impact fuse instead of a selectable fuse. Yellow nose. God do I miss those days. But you nailed it brother. I remember fielding Canister rounds and I'll admit, at 15m you put a can into a house and clear the whole fucking lower floor in one shot.
first one in the thumbnail looks like a middle finger, second one looks like a actual ammunition shell, third one looks like a oversized thumb tack in a shell
