A traditional Army toast is to “absent comrades“ - to those of the unit who died in the line of duty.
We have a lot of such traditions. At what the Army calls a “dining in“ a separate small table will be set with a place setting, a candle, and an empty chair to represent fallen comrades. At a memorial service (which most of us have attended far too many in recent years) the unit’s senior NCO will call a final role with the deceased soldier’s name last - repeating it three times. It is very moving.
From taps, to firing parties, to presenting the flag to a grieving wife or mother on “behalf of a grateful nation,” Memorial Day carries a lot of emotions for those who have served.
I know all appreciate your initial post.
