You gain experience and cash by battling other players. Each battle takes away some of your health too. You must have a minimum amount of health and 1 AMMO point to engage in Battle. The outcome of a Battle depends on your Commander Count, their distribution and the kind of Units they are commanding. In a Battle, whether attacking or defending, the game automatically equips each assigned Commander with 1 each of the best Units of every Class from ARMY, AIR FORCE, NAVY and SPECIALS that you have deployed. Each 1 Commander gets to command at max. 10 Units of each Class in ARMY, AIRFORCE, NAVY and SPECIAL UNITS. If you have CAPTAINS, they will enhance your power by taking extra units in each Class of a particular category of Units. The max. number of CAPTAINS you can have is (your level *3) for each category of UNITs, Army, Airforce, Navy and Specials. The max. number of Commanders that can be engaged in battle is equal to your level.
In a normal battle, the opponents within your Attack range are listed and any player can attack any of them. Each hit will consume a part of your health and Ammo. The attack Range for Normal battles are calculated as 20% of the attacking players Level from Level 20 onwards and 10% of the attacking players Level from Level 0-20.
All the players who attacked you will be listed in the Rival List and they will be refreshed in 13 days. Within that time you can retaliate them without any Attack range barriers.
If there is a player whom you can not beat but is continuously beating you, you can Strike List him with a cash reward of your Choice. The strike listed players can be taken out by other players. But the Attack range applies here. If a player is Strike Listed by more than one player his Infamy goes up and so does his Attack range.
If someone Kills your Alliance member you get to Battle them without any Attack range restrictions.
