Oh, may be all i suggested is a bad idea. I was talking about third cavalry unit.
Most nations have two cavalry units - one hand cavalry (hussars, cossacks, uhlans etc.), and one ranged cavalry (dragoons, ruyters, wagons, etc). But some have got third cavalry unit, which is more powerful, more expensive and availible in age3, e.g. french have cuirassiers, spanish have lancers, british have recieved those scottish cavalry in WOL (forgot their name), russians have oprichniks (ohrana in WOL).
I just suggested to make russian units more historically accurate, cause they are just renamed strelets and oprichniks. Yes, i know, WOL is about more modern period, but strelets and oprichniks were more historical, cause they really existed. I just suggest to make russian units more authentic. If WOL involes XVIII century, why not make unique unit of that period? As I said before, at that time Russian Empire had got tough cavalry units, similar to cuirassiers.
Or, if they wouldn't be "unique" enough, I have idea to make cuirassiers shared units (cause several countries used cuirassiers), and make royal guard upgrade for russian cuirassiers. But probably it should un-balance the gameplay, i just mentioned it.
All i want to say, "Pekhota" and "Okhrana" are just russian words, meaning "Infantry" and "Security" and it's not good idea to name units like that. I suggest to make a unique unit, according to history.
