Thanks for the comments everyone.
wbill: I took the challenge of the kubinka nashorn camo pattern because it's largely discredited as an 'authentic' scheme because it looks so wacky when you take a look at the kubinka nashorn. But having done it up, I wouldn't think the short stripey pattern would really be a liability in the field. As for a base, I guess if I do the figures, I would really need a base because it shows them re-arming the vehicle (and hence off the vehicle)
ausf: I'll keep that procedural point in mind next time I play with winterwash - thanks.
Speaking of bases - is there any on-line tutorial for bases? Like typical procedures for set-up, creating grass, dirt etc. I have no idea how grass would be made. Heck, I don't even know how dirt would be made. Suggestions welcome.
