Unus Offa, both the Vz24 and Vz33 were issued under the names of G24(t) and G33/40(t) respectively. I don't know if they'd be in Stalingrad, but they WERE issued, this I know.
I have a couple more suggestions and expansions on my previous ones, a couple I think could be universally agreed upon.
First one, Gewehr 98 (pictured above). These were used quite a bit, from what I can find. They started falling out of favor in 1940, but a fair number were probably still used in the battle of Stalingrad. I was thinking mods could just be small things like the option of rollercoaster sights or ladder sights and hooded or unhooded front sight. Things like that. I figured it would have a longer bayonetting range but would make you move slower because of it being a full-sized rifle rather than a Carbine.
Vz. 33, under name of G33/40(t), Issued for sure, but numbers not known, don't know if it was in the battle of Stalingrad as stated above. Heard it was mostly issued to Mountain units, though. Wouldn't be too far-fetched to have it. Shorter bayonet range, less accurate at range, but you move faster with it due to the reduced weight. Cosmetic mods maybe?
Vz. 24 has the same background as the Vz. 33, except was probably used more by normal infantry. Would pretty much just be a cosmetic difference of the Kar98k.
P640(b); Belgian made Browning Hi-Power, used extensively by the SS and purchased in good number by the Wehrmacht. 13 round capacity, single action, Modifications could be the ladder sights (don't know if the P640 came in that configuration, though) and the wooden holster/carbine stock.
I'd suggest an animation for the stock similar to that of the bayonets in ROOST.
MP41(r); Captured PPSh41 with magazine conversion and rechambering to 9x19 Luger. Would in all probability maintain the legendary rate of fire of the Papasha, with the added bonus of being able to take ammo from regular German submachinegunners. As suggested, it would have almost identical ballistic properties to the MP40. Uses Schmeisser magazines. Can't think of any mods that could be used for this.
And, this is the one I think will be agreed on.
Probably the dumbest thing TW has done (and I say that with love) is the Hafthohlladung for the German engineer being thrown like a hand grenade and detonating on impact. What? That doesn't make sense. The charge isn't a thrown weapon. It was a shaped charge weapon that needed to be placed on the tank. So I'll suggest a weapon used against tanks that could actually -in theory- be thrown.
The
Geballte Ladung.
You probably know what these are if you're playing Red Orchestra, but if not, I will explain.
The Geballte Ladung was (most commonly) seven Stielhandgranates in a cluster, the six on the outside with the handles removed. They were roughly 3Kg's worth of TNT, and That's all they really were. But they could do was impressive, and they were commonly used against tanks. Now, you might say "but those couldn't take out a tank, they weren't shaped charges!" Yes. You'd be right, but they could take out the treads, and probably do some serious damage if they got under the tank. Maybe they could be a counterpart to Russian Molotov cocktails if those were added in the future. Maybe they could be given to some infantry who get one of them if they come face-to-face with a tank.
I also have some suggestions for hand grenades, but they'll be brief, as I'm lazy as hell. Eihandgranate Model 39s would be a cool addition, as would Russian RDG33 stick grenades. Tripwire has given defensive F1 grenades -noted as such for the fragmentation they put out- for usage in an offensive grenade's role, and seemingly left out the fragmentation of the F1 grenades. So I think the fragmentation should be added, doing the damage of, say, a medium-range pistol round. In the offensive role would go the RDG33 hand grenade. As for the German fragmentation grenades, I would like to see a Splitterring on the stick grenades. Also, I haven't really seen much of a range increase with the Stielhandgranate as compared to the F1. What gives? That was really the biggest advantage OF the Stielhandgranate, the vastly extended range due to the better leverage.
Alright, now I'm done. And I hope this didn't sound too much like me being a jerk and demanding this be in the game because it's my project or something. I feel like I might have a problem with that every once-in-a-while.
