There are a couple of classic marble statues that you could consider soldier like but they are more of a Greek style. The only real sculpture I recall that gives a hint of the "modern" day is the marble casket with the helmet sculpted on top of it. It is an extremely well done monument. Huge but yet understated. Peaceful is an apt description.
As an aside, I had a similar feeling when visiting the American WWII cemetery at Coleville, the one at the beginning/end of Saving Private Ryan. Massive in scale but still simple and understated.
