Well, after a short moment of reflexion, I've decided not to use the "Marine" decals for an aircraft camoflaged for combat over terrestrial landscapes...
So I used "classic" Belgian cockades. Those ones come from a PJ Productions decal sheet. Nice but a little bit of wjite was visible around a part of the red color so, with a fime paintbrush and Vallejo red I had to correct that.
The thistle comes from a decal sheet for the Mirage 5.
Code 26 comes from a old Jan Peeters decal sheet giving codes for Belgian modern aircrafts...
