Do countries like Germany, with rich, relatively recent military history have schools where people go to learn all the different models of bomb that they used back in WW2? How do they keep all that important knowledge circulating for defusal techs after all these years?

Quite interesting

I presume they write it down.

In Germany there's special training run at least partially by the same places that do other kinds of explosives training. And some defusal experts had explosives training from the military beforehand.

There's actually not a lot of primary sources on the reticles used in German armour.

So developers of some of these WWII "realistc" shooters have to design new ones.

I would guess there's better documentation of mines and bombs.

I've actually wondered about that too! My uncle has a bunch of old rifle optics equipment. Very unusual reticles on some of them!
