It's a decent kit, I've built it with several of my children throughout the years. It's come with regular decals, peel type stickers and pre-decorated fantasy markings.
I'd just find an inexpensive set of aftermarket decals and use the camouflage painting instructions for the decal set.
The decals will probably cost more than the kit is worth, but you can find inexpensive ones on eBay or ask on aircraft forums like HyperScale and someone who used aftermarket decals might have unused kit decals from an even better model kit available at a minimal cost.
