Among several integrated sets of Model Air paints produced by Vallejo for common AFV camouflage schemes is their U.S. Olive Drab set, consisting of four color paints, an Olive Drab Primer and a clear Satin Varnish.
Opening the box reveals a vacuform tray holding six half-size (quarter ounce) bottles, each one holding slightly less than half as much paint as one of Vallejo’s standard bottles. The assumption is that the paint set would be one-stop shop, with enough paint for (at least) single project, although my experience with Vallejo paints is that this set could easily be stretched across three or four normal-sized 1/35th scale builds.
