I really dislike oryginal, ugly nato symbols on my blocks, so I made my own version.
You can see the effect on some pictures I added in gallery.
I love it - and it's your choice, if you use orignal or those ones.
I hope, you'll enjoy it.

Just print it as it is.
You can paste those stickers on orginal ones - if you will change your mind, you always can remove them to receive the orginal one.

P.S.
Mainly, I used graphics from Combat Commander Game.
