What is the best support for 3 Knights?

[wulfgar hammerfist]

I have three knights: a Crusader, a Paladin and an Errant that I would love to get on the table. What do you feel is the best way to support them in battle? I've included a few ideas below but I am open to other considerations as well.

 

The Knight gear is fixed since that is what the models have on them.

 

Crusader - rapid fire battle cannon

Paladin - rapid fire battle cannon

Errant - thermal cannon

 

Suggested allies:

2 x Raptor Wings (4 storm talons, 2 double melta speeders)

Skitarri (kataphrons with grav, vanguard with haywire)

Sevrin Loth and some marine support (invisibility being the main theme here)

Legion of the Damned (lots of deepstiking threats)

Militarum Tempestus (lots of deepstriking threats but very squishy)

Xenos (eldar with scat bikes and swooping hawks)

I would suggest skitarii, I think, As they add a lot to the knight army. 2 squads of just 10 man vanguard can wreck infantry and hold objectives, Onagers can provide anti-air with icarius arrays or anti-tank with neutron lasers, And dragoons can deal a surprising amount of damage when the enemy is focused on killing the knights.
