I cut the Trooper on the left's right arm at the elbow and glued it back on so that he can hold his rifle with both hands. The left hand looks to have been designed to hold the rifle. I used Milliput to fill in the gap on the arm. I gave the figure a wash with thinned out green, and some thinned out brown around the bottom of pants to look like mud. I also gave his helmet, backpack and gun a wash with grey to bring out some details. I had to cut the stock of the gun off so the figure can hold his gun right. I used yellow sculpey to make the beard.
The figure on the right is simply a repaint. I gave the figure a wash with dark green and washed the helmet and backpack with thinned out black. It is kinda hard to see on this scan.
