I was on a bicycle trip this afternoon and I passed the post office. As I saw that there was no queue I dropped in and fetched my parcel with the box of Chaos Terminators.
With that I could build the last three ones for my 5 men squad:
I think I'll change the bolter arm of the Sergeant (the one on the left) to an outstretched one. And I'll turn the horns of his helmet skywards.
