Educate this noob: Why is with some queued platoons?

churchill50: When I platoon, it's to play with friends. That means that we each just pick the tank we feel like playing. If those tanks don't work well together, or we are placed on a map where they aren't going to work well in the same place, then that means we play in different places on the map.We're still working together to some extent. We'll tell each other how the fight is going on our flank, anything important we feel like the other should know (like a tank that disappeared from our flank and is probably rotating to the flank a platoonmate is on), and in the case of a carry where only 1 or 2 of us are still alive, we'll feed them information about hitpoints of remaining tanks and talk through options.So we still work together, but we may or may not be on the same flank.
