Thank you for your kind comments.

I've used Ammo's #68 (IDF green or something like that, I am not sure of its name), mixed with Tamiya XF-2 Flat White. Several layers with different mix rations were applied, with chipping fluid being used between these layers. It was my first attemp in using Martin Kovac's "distressed" method (you can check his youtube channel, Nightshift, for a detailed walkthrough).
Cheers
