That's an option, but I look at it this way:
1. With that armor I can blitz and take more territory, faster.
2. I usualy bring 2 Infantry from Southern Europe for the attack on Egypt, which can be used to suport the new armor in attacks on South Africa and/or Syria.
3. 3Infantry in Finland might delay an occupation a little longer. It is a temptation for Russia to attack the armor to remove it as a threat to Karelia, where as they might wait and let Britain or america remove the less threatining Infantry. This translates into a possible couple extra IPC's. Of course this depends on your opponent.
