I doubt the "Special War Powers" refer to an entire organization, if it did, it would most certainly include the Royal Guard. Yhwach had the Gotei on the ropes and retreated, more or less due to the risk of their appearance. I would assume he has an "elite of the elite" to combat the royal guard. Possibly of higher rank than the stern ritter. I would guess his little buddy Haschwalth is one.

I would assume Yhwach might two War Powers on his side. So here's my list. 1. Ichigo Kurosaki 2. Zaraki Kenpachi 3. Haschwalth (seems like he would be one, seems pretty strong) 4. Unnamed Quincy of some sort ~ A unrevealed character. Or Ishida. 5. Inoue Orihime.
