Leader-Hero can add IFP or LM to attack, but IFP will always be at least 1, so unless its IFP is 2 it's just a wash. He's a Leader, as stated on Skill text. Leadership Range is part of 11.1. No Leadership penalties when wounded: LM and LR remain 1. Seems all pretty clear here, guys. During Rally Phase he has the LM to subtract from other units' rally attempts. He's just a badass Leader. No Shaking, and some with an IFP of 2, various Ranges and Morales, etc.
