@Alexander
yea Tank placement follows oob rules except for Mass Tanks and Total War Tanks. They place in Moscow, although technically you could upgrade to a Major and place Total War Tanks.
yea I usually arm them at end turn. Delete the unarmed mines and then edit in the correct Changer mine. Most high use areas have border specific ones.
If you can’t find the one you want just use a generic one and say in the comments where it’s defending.
The Game Notes explain it fairly well. I think I need to update it though.
Ahh … you are asking about the 10 bucks you get. Yea you can place a Tank in any TTy that wasn’t attacked. It’s just the specials like LMs, Rockets, Commisars, TG etc… that can only be placed in Moscow that can’t be placed anywhere.
