Many countries have erected a memorial dedicated to those soldiers whose bodies were never identified. Anon would like to see a nation at their country's tomb, paying their respects. I don't care which nation you choose (so long as that country has such a tomb. There's a list on Wikipedia, if you're not sure), but please, leave the soldier unknown; I don't want them to somehow know who it was just because they're the nation. I'd rather they be paying their respects for all the men and women who've died and never made it back home.

If you include multiple characters interacting, no romantic relationships please, just platonic support and understanding.

Bonus 1: "Related" nations (i.e. FACE, the Tomato Gang) going to someone's memorial together.
Bonus 2: If it's a memorial that is always guarded, then the nations taking a turn as guard, complete with the uniform and ceremony and everything.
