"That’s an entire other subject, including how the armies had to invent modern hand to hand combat training." From what I read about the german infantery in WW1, is that most troops learned about the technics about effective hand to hand combat only on the frontlines, directly from the Frontschweinen (frontpigs, veterans). Who told them mostly, that what they learned in the drills with fancy bayonett swinging, they should forget and just use their sharpened shovel. Or a rock, or a grenade to hit with it. Anything. By WW2, all those was integrated into proper infantery training. Improvised, brutal and effective. But the modern german army, doesn't teach hand to hand combat at all anymore, except for officers, special forces or military police and as far as I know, also only in a very limited way.
