A Level of Silence and Respect.

[Rashid.bk]

Thought I'd share this if you haven't seen it. Tomb of the Unknown Soldier.
A sentinel reminds visitors of the place where they are at, and in case you are wondering, their weapons are functional.

The Sentinel does not wear rank so as to not outrank a soldier at rest. He is under the "command" of those which he guards, his duty is unequivocal and beyond reproach.
It is a place of Honor.
I always take a moment to reflect on those that are no longer with us, life is fragile. I have said goodbye to many, but we will reunite one day.

And remember, there is always a new threat, and our boy and girls are still out there right now trying to keep it away....
