Actively target floors with one team, pause the other team to allow suppression to take effect then move them up.

Lucas, I don't think you are getting this.  No one is complaining about enemy reinforcements per se, but if they spawn in on top of the player it is a flaw in the scenario.  They should either be spawned into an area that the player won't have reached yet, or they should start the game in dead ground and be triggered by player movement on the battlefield.

Let's say in the real world you have a ridge line on your left flank where you could place your reserve tanks hull down to deal with anything that came from that direction.  Can you tell me how you can use them to protect your flanks in the game version of that scenario, when they can't see off the map edge and enemy reinforcements spawn right on top of them?
 
Of course you can't, so it seems pointlessly bone headed to argue that a design flaw in a scenario is somehow replicating real world circumstances.
