You were right BabyDuck, I was trying to move in object mode, not world, that is why I couldn't snap to the grid, thanks.

I have added the top of the leg guards and also extended the chest plate down farther as I realized that it is probably all one piece. I think I will have to go back and smooth some of the spots that come to a sharp point like on the sides of the hips there is a sharp spot. Comments and Criticism are welcome. Thanks.
