I'm still upgrading my factory to unlock the APC but I was wondering how those people who already have it are using it. I have yet to be attacked by one. I like the idea of a unit that produces more units for long battles. I was wondering if people deployed them with their regular armies to stay in the large group or some other strategy. The ones I received in the gift event I would generally drop them right after my first rally and usually away from the main army. That seemed to work well but I only used them in war so I could never really watch to see how they did. How has anyone here used them effectively?
