If there's one down side to LEGO, it's that the minifigures and scenes are static, typically. Showing action requires camera tricks or mechanical instruments. Solving this issue is just one of the fun challenges of creating custom accessories. That's why the Arrow Half is such an ingenious accessory piece; it shows action even if it's not in motion. You can see that there isn't just about to be a battle, there WAS one and these poor souls were on the losing end of it and they've got the evidence still stuck in them to prove it. The Arrow Half fits in to any item with a stud, including shields, armor, and helmets.
