Thank you for your nice comments gents!
1. No, they were issued at company level in dangerous situations.2 Questions that have to be asked:
1. Were all of these trench helmets when issued ...I would assume, that they also came with this frontal armor,,
2. Were these used for machine gunners..or just to peek over the trench so not to get shot in the head?
2. This could of course also be for machinegunners, but not nessecarily...
Yes, they did. The stirnpanzer was meant to have less head injuries, which could also be caused by pieces of schrapnel and other debris. When taking a frontal hit of a bullet, it was very likely that it would penetrate the stirnpanzer and the helmet, but I suppose when the bullet hits under an angle, it was probably just deflected...Did they actually Work, I wonder?
