The movement phase is fairly standard except that a units movement points are actually determined by the season the game turn represents. Combat is resolved by the traditional odds modified by terrain and cross referenced with a die roll on the combat results table. One twist serves to give the game a slight tactical feel. However, in defence, they cancel the combat strength of any attacking armour or air support units respectively. They cannot be used in this manner in assault.
Supply is handled differently for both players.
The Nationalist player generally does not have a problem with supply and simply traces a traditional supply line to a friendly source. Historically, this was thanks to the support of Messers Mussolini and Hitler. Despite Soviet aid, the Republicans have a supply creation phase. Once again the number of friendly cities held effects play, this time in the number of supply units received. A supply unit is expanded for each single assault or defensive combat.
