Leaning Shit House means: The insignia for the First Corps Support Command 1st COSCOM is a round U.S. Army patch. It depicts an arrow with the shape of an outsidehouse. It is positioned at 10 PM, which means that the mission can always be completed before midnight. Airborne Corps units under 1st COSCOM command wear an Airborne tab over the patch. The insignia then is known as the “flying Leaning Shithouse”. (in Community Dictionary, added by Jorge Wall)
