You just answered your own question. This game, Leadership/Command applies to all units on your side. In Part 2, Endgame, your commander is Elincia...she has 3 Leadership Stars, giving all units +15 hit and avoid. In Part 4, Endgame, your commander is Ike...he has 3 Leadership Stars, giving all units +15 hit and avoid. That is it.

OH.
Okay, that makes sense now. For some reason I was thinking that only units with the same AFFINITY as the commander got the leadership bonus. It's the AFFILIATION, not the affinity.
Heh. I feel dumb now.
Thanks though! It was driving me and my stat-geek self nuts.
