Well, that's the problem here. The posing is quite horrible, indeed.
First two pictures reinforce my conviction.
Also, we have been giving constructive criticism (Though it looks like a bunch of the comments just say "bad posing", so I see what you're going at).
TF2 Blood spatter is your problem, I have it mounted, and I don't see your blood issue.
A lot of "mistakes" are intentional, realism-esque features.
Edited:
And by the way, that's how WWII soldiers charged, at least how the Soviets did.
"omg der not takin covr dey chargn in2 gunfir!" I know, because THAT'S WHAT THEY DID.
You can't be serious. This isn't realistic at all, that's, quite frankly, a lame excuse to compensate for the flaws of the image.
We never said anything about the logic of them charging into gunfire. We're talking about how totally unserious you've made the picture with your posing.
So, here are your errors, piece by piece.
Picture #1: None of the people in this image have a realistic posture at all. The guys getting shot look as though you simply randomly spread out the limbs with the physgun. Also, you can see the second picture in the background, something you should definitely avoid doing, ever.
Picture #2: The officer looks as though he has a spinal disorder, tuck that ass in. None of them are holding their guns right (or are fingerposed anywhere close to where they should be), they're staring into space, and they're really not doing much at all in this picture, becoming a waste of screenspace. The officer seems as though he'd be the only thing in this picture worthy of merit, but even he's severely flawed.
Picture #3: Guy clutching his face is clipping into the ground, guy on the left with the PPSH-41 can't hold a gun correctly (like everyone else in this image), nor can the guy in front with the SVT-40. The flag bearer looks decent, at best, but the utter crappiness of the rest of the pose negates any of this.
Picture #4: A German Machine-gunner would not place the stock of the machine gun over his shoulder; this isn't a rocket launcher, and his shots will be blasting the tops of the houses, if that (I suspect that he'd be more likely firing into the air). I'll ignore the fact that he's holding the gun with the wrong hands, and focus on the holding as is. His right hand, which is clipping into the gun, would never be holding the barrel unless he wanted to burn his hand, and he would be holding it on top of the assembly to stabilize his aim. In addition, his left hand is nowhere near the trigger, pulling an invisible bolt on the gun. Even suggesting that this is a realistic posture is fallacy, and pure bullshit, in blunt terms. Also, the background's crappily posed guy getting shot further detracts from the image's overall quality.
Picture#5: This one is marginally better, with the German's posing hidden entirely. The Soviet soldiers' posing, however, ruin the image, especially the front man and the man on the right getting shot.
Picture #6: The issues I presented with the machinegunner are even more evident here, not to mention that the guy getting shot looks like you slapped on the blood. Also, the way in which he's flying indicates that someone fired in a spot somewhere below the sandbags in the ground, which is physically impossible in this case.
Picture 7: Overall quality is Okay at best. His hold on the gun looks rather unrealistic, and the magazines are almost entirely off of the crate.
Picture 8: Grenade guy looks rather sloppily posed, and the man getting shot in the background further ruins the image.
Overall, I think that the guy getting shot in the front part of the charge is a huge problem in all of these images.
In short: Work on it. A lot.
