Here's the prototype with empty hand and Sgt's Power Sword.
And here's one squad of my Lightning Claw Terminators. The second squad is that pile of bits you can see behind the prototype in the above pictures. I've decided only the Sgt will have the heraldry shield. You'll also notice the right shoulderpad is missing. I'm going to wait for my Forge World Blood Angels Shoulder Pads to come in for that (but I need to order them first!).
