Most soldiers know each others' hardships,whilst HR is only concerned with the corporations' interests and never your own.I like how the SS-Commander is better to his underlings than your regular HR-department.
I wonder if Katayama found a source that talked about the E but showed a H1...Translation says Ausf. E, but the model drawn on the page is more akin to that of a Tiger H1. The Ausf E had a smaller cupola that made it harder to hit. Smoke grenades are still also present, which were removed in the E variant. There are a lot more subtle differences between the H1 and E, but those are the more notable ones.
