Do the 'Special' war battle units do anything special?

[bookwormbabe29]

I'm at the defense of Lelcar, and organizing my units (finally figured out to do so, embarrassed to say lol) and noticed if I put Kisara, Logg, and Lun together the ship becomes a 'Prnt/Cld" (Parent/Child I'm guessing) Arcship. Does this add anything? Any other nifty combinations like this?

EDIT: Lindwurm Cavalry/Ram with Wilhelm/Mueller.

It does'nt give you anything, just a nice little theme for your army.

Edit :

This is the list of all known combination :

Logg + Kisara + Lun = Parent/Child
Bernadette + Yahr + Nelis = Island Nations
Volga + Wasil + Orok = Lelcar
Wilhelm + Mueller = Lindwurm.
Isabel + Mathias = Maximillian
Roy + Faylen + Faylon = Bandit. Roy must be the first character.
Isato + Urda = Elf

I think Craig,Roog and Rahal together named Dragon Cavalry but i'm not 100% sure
