I can relate to this since I was a military brat. I like this and the sense that one person out of the corp is everything to one person. However try tightening things up a bit without loosing your measured structure.
One man stands still in the crowd; (7)
A statue, frozen in his time. (8)
One man crawls across the ground;(7)
A soldier, fighting for his name. (8)
One boy asks, “Who is he?” (6)
A message for all to see. (7)
One boy knows who he is;(6)
My father, I know that smile.(7)
Your message would still be the same, but the stucture flows a bit better and is more uniform. The suggestions are there, take or discard as you choose.
