Strategist

Effect: 

You rely on planning, teamwork, and calm execution of orders as a commander instead of charismatic presence. Any time an element of the commander class refers to Charisma, you can replace that element with a reference to Intelligence. In addition, you start every battle with 1 additional command point.

Adventurer Feat: 

You gain 1 additional point in a background related to military history, strategy, command, or warfare. You can use this background point to raise that background beyond the normal maximum of 5.

Champion Feat: 

When you roll a die to find out how many allies one of your commands or tactics targets, add +1 to the result.

Epic Feat: 

Once per day as a free action, you can gain a number of command points equal to your Intelligence modifier.
