Soup sandwich

[Becky]

A term used in the US Army to denote extreme uselessness. It is directed toward something or someone that is the figurative equivalent of the literal [hot sloppy] pile of shit that a gob of soup between two pieces of sandwich bread would be.
So the implication here is that the object of discussion is Fucked up like a soup sandwich.
[Equivalent expressions] in the civilian world are:
[Tore up from the floor up].
Useless as tits on a boar..
and so forth.
