The surprise hits of my Skitarii force. When I first saw these guys all I could think was how poor an AV 11 walker would have to be. But at 45 points a piece with a 5+ cover save all the time they are more survivable than you would think. They are easy kill points if the enemy wants to kill one. But with some much scarier and much tougher units on the table (read Imperial Knight and Ongar walkers) these guys actually tend to hang around and get some work done. The formation also helps as they don't start on the table but do get to roll for coming on turn 1. The rest of the formations benefits are meh at best. Re-rolling wounds against a single unit is decent but doesn't come up often. The army has few units so I ran two of the formation with minimum squad sizes. We played maelstrom missions so being able to get all over the place was best. As you can see I used the second style of painting up taser goads, using my airbrush, on all these models. It came out really well. A little heat weathering on the laser cannons and exhausts on the walkers also worked well.
These second unit is pretty much the same but I changed up the decals on the hull plating to help distinguish the two formations from each other so I could play them correctly. Being able to shoot thru the formation at no penalty (no cover save to the target) for example would not work from formation to formation. I was able to do some magnetization but only with every other model due to the parts. So with that in mind I opted to magnetize only the ballistic ones as I felt they are the worse of the two options. As such all the hooded drivers are able to field the melee weapons, lascannons, or autocannons. In all my games these units did a lot of work. Against my round two opponent who fielded a Space Marine battle company complete with many free transports they performed magic. Not typically able to smash targets on their own they made nearly half his army have to turn around and face these models rather than come down my throat. Better yet, they mauled the half that came to deal with them, killing almost everything but a couple of the unit and holding them off for most the game and leaving the survivors way out of position. This let me overwhelm targets on the other end of the table (we played hammer and anvil and these guys came in on my opponents deployment area). For 290 points these 6 units did a great job harassing the opponent. In other games they helped to shore up assaults in progress or harass backfield units. Really if they where not so expensive $$ wise I would definitely field 12 or more of these guys. They just work to well for the points.
