"For Vulkan, For the Emperor" - Trooper So'Lak of the Salamanders, or he could be an Alpha Legion infiltrater?
I feel there should be some Shattered Legion troopers scattered amongst the loyalist forces hoping to reinforce their own brothers when they finally meet up. Though as he hasn't removed his helmet so he could equally be a spy for the chaotic legions.

Min = 10 troops inc vet all with bayonets (110 points)

Max = 14 troops, vet Sarge with Power Fist and Artificer Armour, a scanner/vox, a vexilla and bayonets. (209 points)
