Basically this consists of painting all the larger flat upper surfaces with a lighter tone and leaving the dark wash areas alone. It looks crappy up close but nice from tabletop distance.
I did this because I feel the usual "edge highlighting" looks unrealistic on vehicles, compared to on infantry. And the other day at the gaming shop carpark I was struck by how vehicles are always really bright on the roof/bonnet/boot.
I named it Task Force Andromeda to remind myself to playtest the Fireteam Andromeda rules next time I take out my 15mm toys for some exercise...
Antenociti makes the best APCs in 15mm
The mecha are Rebel Minis (who have the best postage rates in 15mm) chosen for their vaguely Soviet feel
The recon squad travels by scout car - again from Antenociti. You can see where I have avoided the places where ink has pooled (like roof hatches) to exaggerate detail
The infantry is by GZG. The whole platoon was hastily painted in ~2hrs between long stints of being forced to play in my toddler's sand table. (She's bossier than her mum!)
If you want to see the opposing force (and how lighter paint schemes look better), see Task Force Weasel.
