Multiplayer Modding Question

[Epaminondas]

I have a modding question of sort too; in fact, I posted it on the modding forum, but let me try here as well, given that there's more traffic here.

Basically, how do I change unit stats for various national units? Again, I just want to change unit stats, and nothing else. Quite simple.

Also, anything that I ought to be aware of? For instance, whether future patches will restore the original unit stats, and I have to re-do the whole process, etc.

Thanks in advance.
