What if when units were sent they would cost resources to deploy.

Like infantry would cost some ammo and plenty of rations and drones would cost very little rations for drone control but more ammo than infantry. Armor would cost fuel and ammo and aviation would cost more ammo and fuel, deployment costs would keep overpowering alliances from picking on smaller ones to much and this makes it so infantry are still valuable as they cost less and take less to deploy.in turn,it would also make the game more "tactical"
