I started '73 with SU and it's now 80s. I still have their original gear
But I don't know is it worth yet to update, only real new thing is RPG-7v and newer guns. I believe just new rifle doesn't affect a thing, right?
Infantry updating is a piss thing. You have to view from other menu what gears they have and then go to update menu and click the right section what you were looking at.
It would ncie to have some kind of easier update menu so you could update entire platoon with option you want, instead of clicking in tens of different menus and unit screens.
Other question, does AI get more points for upcoming battles if I increase my core size?
