PaK ZiS-2 57mm Damage Issue?

[OMGPACHIMARI]

The PaK ZiS-2 57mm doesn't do HE damange, and thus it cannot shot at infantry. Is this intentional?

I have about 200 hours playing, and this is the only unit I've found that's like this. I think every weapon in the game does HE damage except for this one.

Yep.

The ZiS-2 was conceived strictly as an anti-tank gun and was only designed with the BR-271 AP shell (and variants) in mind.

Early in its development, the ZiS-2 was provided with canister shot, but they were only effective up to a range of 100-200m and everyone quickly realized what a complete waste of time that projectile was. :b

As explained above, it was AT only, no HE round.

Yeah I noticed that aswell, which is weird, with a quick search it seem the Zis-2 had access to the УО-271 fragmentation round.
I haven't done more research on the subject and unfortunately don't have much source on this matter.

Thanks! I appreciate the history as well. I was mostly just confused because the weapon has the HE trait.

There. zis-2 should have high-explosive. both in WARNO and in Steel division II.

УО-271, УО-271У, УО-271УЖ(afterwar) with 218, 204 and 220 gramm of explosives inside respectfully. У(Унитарный - Unitary) О(Осколочный - Fragmentation) 271 - index of weapon system in artillery agency. It is a bug in my opinion. Devs have other reasons stated above. For shell information check almost any ww2 source as this gun was widely operated and used as infantry support.
I would recommend Краткие таблицы стрельбы 57-мм противотанковой пушки обр. 1943 г. Бронебойно-трассирующие снаряды. Подкалиберный бронебойно-трассирующий снаряд. Осколочная граната длиной 4,2 клб., 1943. - 32 с.
(Brief firing tables of the 57-mm anti-tank gun mod. 1943. Armor-piercing tracer shells. Sub-caliber armor-piercing tracer shell. Fragmentation grenade 4.2 calibers long, 1943. - 32 p.)

According "Shells for 57-mm guns of land, tank and mobile artillery"(1946) ("Боеприпасы к 57-мм орудиям наземной, танковой и самоходной артиллерии") there were only 3 other type of shots available (aside from canister round).
They were:
1. Solid shot UBR-271 with 57-mm AP-T shell with MD-5 fuse or UBR-271SP with solid AP-T shell BR-271SP (1. Унитарный патрон УБР-271 с 57-мм бронебойно-трассирующим снарядом со взрывателем МД-5, или УБР-271СП со сплошным бронебойно-трассирующим снарядом БР-271СП).

2. Solid shot UBR-271P with sub-caliber AP-T shell BR-271P (2.Унитарный патрон УБР-271П с подкалиберным бронебойно-трассирующим снарядом БР-271П катушечной формы).

3. Solid shot UO-271U3 with new fragmentation grenade O-271U model 1944 with KTM-1 fuse. (3. Унитарный патрон УО-271У с новой осколочной гранатой О-271У обр. 1944 г. со взрывателем КТМ-1).

Not HE though. ;)

I haven't found any accounts of O-271U field performance; I'll do some digging and see what I can turn up.

It's the terminology confusion. In russian artillery anything could be called grenade. For example RPG-7 rounds are called Реактивная(Rocket-propelled) Противотанковая(Antitank) Граната (grenade). So essentially "Fragmentation grenade" - is HE-Frag just in another words

Performance was not great. I would say 0.57 HE in terms of game would be enough. It was high velocity gun with ability to pin down foxholes.

Good info, thanks.

Although I wonder at that point if such a low HE value wouldn't just be a waste of ammo that could be better spent shooting at (light) armor.

It has 50 ammo currently in game. Given RoF of 15 per minute it's 3 minutes of non-stop fire. It's more than enough for meme-tier unit
