The infantry looks to be a dual kit with ranged and close fire support options. Weapon rules are still lacking so there are still quite a few question marks as far as how they'll work in the game.
Additionally there looks to be a walker dual kit on either a large round or large oval MC base. I would expect these walkers to be Squadrons (they are!)
Edit: More Rules!
The Dunestrider rules makes these guys pretty fast, and the Dragoons could be a very speedy assault unit with 9" move and +3" to their charge range. And only 45 points makes the flimsiness of the 2HP AV11 frame worthwhile.
