I skimmed through this thread, so sorry if I restate some things.
Without Bravery, my riflemen get suppressed pretty much right when they walk into the range of an mg42. After I got Bravery, I am able to walk to the edge of an mg42's range and walk back out without getting suppressed. This might have something to do with my rifles being more vetted, or maybe my reaction time has gotten better, but nowadays my rifles rarely get suppressed by an mg42. 10% suppression resistance is small and it won't let you walk through an mg42, but it definitely helps you avoid getting suppressed RIGHT as you walk into the firing arc. I'm not sure, maybe someone else has different experiences or maybe the stats say otherwise, but I post from my own experiences and my 17 riflesquads in my company rarely get suppressed unless I want them to get suppressed for a flank.
Personally, I think these abilities make your opponents have to think more about their mg placement. With these abilities, you can walk into the range of any type of mg and walk back out without getting suppressed, as long as you don't linger in the LoF too long. Setting up an mg in the middle of a battle is already a great tactic, and these t1's make it almost necessary to do it.
I think those players that don't notice the difference from these t1's are either too rambo with their riflemen or they don't use hotkeys and therefore are unable to run their riflemen back once they run into an mg.
+1. I found that there is a difference. It took me a while at first to notice it but yea, certain things dont suppress you. I need to get it back i miss it.
