You can locate the battle level (where you can also find more information about leadership points and upgrading your troop cap) at top left corner of your screen while in a battlefield: 

• Leadership is represented by the little white flag icon.(The two numbers next to the white flag represent your used leadership points and the current total leadership points.)
• Leadership points decide the number of admin areas you wish to capture and you can improve your battle level to gain more of these leadership points.
• Tap the + icon beside the little white flag icon to convert your resources into leadership points within your Command Center once your battle level reaches 10.
• To increase your troop cap simply upgrade your cities to lv10. Tap the + icon located next to the little white tank icon to check this out. (Please note that every level 10 city increases the troop cap by 2)
• Successful upgrades for your battle level, leadership points and troop cap depends heavily on completing more battlefield missions, defeating more enemy troops and destroying more buildings.

• Also note that the maximum number of the battle level/troop cap/leadership is 99/110/104 respectively.
