Trojans from the 9th Necromundan, Blue company, White squadron await orders to redeploy.
So far my ideas are:
Salamanders (though I would love to put a guardsmen in the back with a heavy weapon)
Deathstrike Missile Launchers (but I might add a bit more detail to the missile launcher, as it looks like it's a cut down 28mm mortar, and not an epic scale launcher).
I am also planning to get some artillery carriages like Basilisks and Medusas, and keep the guns removable. That way I can use them as towed artillery with the Trojans (Krieg style), or put the guns in the back of the Trojan, like I did with the Deathstrike, to use them as mobile artillery, like Basilisks (Steel Legion style). So I'm looking forward to that!
