A couple of questions on the game engine mechanics ...

[Ricky B]

I hope it is possible to chime in with an additional question: if the replacement rate is something like 1%, but a unit has only 10 vehicles, how do replacements work?

So 1% of 10 would be 10% - so it would have a 1 in 10 chance of a replacement arriving. Almost everything in the game is calculated this way, and the docs will generally state how it works if not this way.
