Now he looks like one real son of ...... the desert!  fantastic work, ak615, and like many others, it really does push some buttons for me! 
Action Man and Infix were my life!  Every week, my pocket money was just enough to get me a box of small soldiers, or a plane, or a tank.  The artwork like that on the boxes of AMan is indelibly printed on my retina!  I recognised the poses in your beautiful drawings of those Commando and German figures straightaway, 327! 
I'm not familiar with the BISG, (although, I did graduate to big soldiers!) but again, I love the use of color on the box.  Great thread!
