Here's the second Tactical Squad. As with the first squad, the models have a mix of modern Mark VII, Rogue Trader-era plastic accessories, and Mark V armour from Forge World.
Sergeant with Plasma Pistol and Power Sword.
Heavy Weapon marine with Multi-Melta.
The Special Weapon marine from this squad is actually a pilot: the helmet and torso were taken from the Storm Raven sprue that I got with my Storm Eagle. The story I've come up with is that he is a pilot whose aircraft crashed, and who has joined up with this squad to replace a fallen Battle Brother before he can return to his airbase.
