Orions!
And in more detail:
Oldest, lead mini in generic camo, a complement to the ON1-VA - I'd have sworn there was a canon model which drops the SRM-4 for more armour & ammo, but can't find it now. Next, a Magistracy Cavaliers unit, CityTech plastic in ON1-V configuration. Next to it, another ON1-V - lead this time - in Orloff Grenadier colours, and then a Hansen's Roughriders camo CityTech ON1-M.
(And yes, the SRM is in the arm, the way nature intended.)
A ralladium Ryuken-Ni ON1-MC; I went representative with the missile tubes. Behind it, a Lance Pack ON-1MDC, with the second cockpit above. Thirdly an Atrean Guards ON-2M, and finally - and why not? - a Perseus D config. The D normally has no weapons in the left arm, nor a hand actuator - I thought that looked a little silly. It is an Omni, after all.

Edit - better now?
