I understand the limitations of where you can place units when they come in from reserves, but am a little lost on what exactly can go into reserves, and when they come in. 1) Are you limited to only placing units in reserve that have the Reserved or Airdrop rule? 2) Do you choose what turn your reserves come in? Is there any turn in which they automatically come in? The reason I ask is the last couple games we've played, the scenarios (both out of Zervograd) both would be almost an auto win if the allied player reserved particular units via airdrop or otherwise. We feel like we are missing something with the reserve rules.
