Could some of the more seasoned veterans of reenactment share how their groups handle grenades? Pyrotechnics, foam/wood replicas, reputable sources, how to behave when a grenade 'explodes' near you, how they were carried by british/us/luftwaffe/heer forces etc?
Specifically for me the most important questions (for me) are:
How would a WWII British infantryman chuck a Mills Bomb? Would he yell anything?
How many would he carry?
Where would they be carried?
What is a good source of foam/rubber mills bombs that ships outside the UK?
