The Four-Color Figures blog has a preview of the movement bases that will be used in the 15mm sci-fi Galactic War rules.
From their website:
The basic squad in Galactic War I is called a Unit, and 3-6 units usually make up a Force Element. A Unit normally consists of 5 infantry models on move base of some kind. Blue Moon plans to release plug-in resin move bases for just this purpose. Pictured below is a Ferreen unit on a mock-up of a move base. Notice that the unit consists of 4 Ferreen and 1 War-Orb. The Ferreen use their Focus Unit gauntlets to direct the destructive energies of the War-Orbs in battle.
