Ok so ive been working on my Vostroyan IG army and i was thinking of cool things that i could put in the force that could do a job not done by anything else in the army.
At 1500 points ive got 6 vet squads 3 in Chimeras 3 on foot. And also 3 Leman russes, 2 standard 1 demolisher/Vanquiser (not decided yet) And one unit i have always loved is Kasrkin and Stormtroopers, they are just extremely cool models and i love the idea of them coming onto the battlefield in a Valk or Vendetta.
Tactically i would have 10 of them with 2 melta guns, their job would be either to hunt tanks by jumping out next to a tank, or by dropping themselves off near a tough unit with armour 3+ so that their high AP weapons could chew right through them.
Although quite pricey i think it could be worth a pop, also the fact that a low swooping flyer unloading elite guys with super guns could be very cool.
