Mind you this is just one guys opinion and it's worth exactly what you paid for it but here it goes;

That particular image is very poignant to people who have stood in formations where that very set up is representative of fallen friends. I know several guys that have the same image along the names, initials or dates. It's not just a symbol to a lot of folks. It's the last representation they had of friends. If you haven't stood in those formations, I think it would be an inappropriate tattoo.

But like I said, that's just my opinion.
