The figures in the first entry are very unusual. Who makes them and what are they and what do you use them for??? 
The figures are Clan Elemental Battle Armours from the Battletech universe, made back in the day by Ral Partha for Fasa´s infantry skirmish game "Battletroops". There were also some mechwarrior figures, plus Steiner and Kurita infantry. All very, very nicely detailed; as said, I also own a platoon of Kurita troops plus heavy weapons which I´ll need to assemble some time. The Elementals are genetically-engineered power-armour infantry; the figures above, in 25mm scale, measure about 45mm sole-to-top of head (I mounted them on 40mm GW plastic bases for stability).
I do have the original Battletroops rules lying around somewhere, but sadly, as with many Fasa products, you´d need an MIT BSc. to make any sense out of it.

Jokes aside, they ain´t half bad, but I prefer something simpler; we´ve used them with Stargrunt and other Scifi-Skirmish rules.
