It would really be a considerable relief if we had a battle group administration. Here we could put together our squads for the individual BR I to BR V in battle groups ourselves and then send them into battle with just one click. That would be a clever solution in the context of “Quality of live”!
Please think about it. It would improve the game considerably.
(Please don’t mind that the same unit types always appear in battle groups III and IV. This is simply because I sorted them in order and didn’t want to put them together differently for this picture. It would have been too much work)
