I finally finished my jetbike command squad for my Iron Hands using the now OOP Iron Hands Mark III Torsos, Shoulder Pads, and Heads: 

Their weapons and shields come from a variety of sources: 

1. The power maul on the left model as you look at the photo is from the new 30k melee weapons upgrade set. 

2. The power fists are from the Mark IV kit. 

3. The banner is from the old Cadian Command Squad with the detailing filed off and a brass rod as the banner pole. 

4. The hand the holding the banner is from a set of Mars Pattern Rhino tank gunner arms with a hole drilled through it. 

5. The combat shields are from the now OOP 40k assault squad (the most recent version of the kit).

6. The power maul on the right model as you look at the photo is from the Ravenwing Command Squad.
