I got the scheme from Google images. I typed in Leopard 2 A6 winter camo and something similar came up. Admittedly they were Norwegian, but after my friend challenged me that I couldn't do it, I wanted to prove him wrong. If I had Norwegian markings I would have put them on, but It didn't much matter. I didn't want to pay more for a decal sheet than I originally paid for the model off of eBay. Plus, I tried new techniques and learned new things.
