Whole 'nother story, valid disability benefits are earned but medical retirement might be otherwise.
[I have friends still trying to get above ten percent for life threatening disease - that is another whole 'nother story.]
My gripe is the retired LtC or MSg collecting retirement equal to my salary, plus a second salary and eventual pension from the same "major aerospace company".
THAT is someone who does not need my contribution.
In practical terms, these contributions are going to go to whomever you send them.
From your comments, I’ve pretty well figured out who you would not choose.
FWIW, the last time I used this service I sent phone cards to a Marine Warrant in charge of a heavy helicopter maintenance company.
