At around $5 a bottle, Military Special (Cheap) Rum is available to active & retired service members through the Class VI (Booze) Store. Class VI is a category for luxury items in the Army although there are those who would argue hooch is a necessity.
As a dependent (Kid), I grew up on generic food from the commissary (Grocery Store). Cans came without labels but with simple descriptions. "Coffee, 16 ounces, ground" or "Beans, Green." We were ahead of Costco with food items coming in huge #10 cans (Six Pound Can).
Today, 'BOHICA' (Bend Over Here It Comes Again) is popular with today's infantry. The same frustration was expressed in my day with, 'The Army's screwed me so many times my ass resembles a #2 pencil in a #10 can.' (Poetry)
