The Department of Defense is known for its military terms, abbreviations, and acronyms. How the heck are you supposed to know what all those letters and weird words mean?
This list is not meant to be comprehensive for every acronym, but it is supposed to hit all the financial ones. So let me know what I’ve missed!
AAFES: (pronounced A-fees) Army and Air Force Exchange Service. Runs on-base retail establishments. Usually AAFES refers to the main non-commissary store on an installation. Sometimes also called “Post Exchange” or “The Exchange.”
AIT or “A School”: Advanced Individual Training: Further training after initial military training. This is where a service member learns to do their exact job.
BAH: Basic Allowance for Housing. An allowance to offset the cost of living off of the installation. The amount is based on the service member’s pay grade and duty location.
BAS: Basic Allowance for Subsistence. An allowance toward the cost of the service member’s food. There are different BAS rates for officers and enlisted members.
BCT: Basic Combat Training. The Army’s first training school. Also known as “boot camp.”

CO: Commanding Officer. The person in charge of a unit.

DECA: The Defense Commissary Agency. They run the commissary.

DFAS: Defense Finance & Accounting Service. DFAS is responsible for pay for all DoD military and civilian personnel, retirees, and annuitants.
Dependency Status: Whether the service member does or does not have dependents. A service member either has dependents or does not have dependents.
Dependents: The people who the Department of Defense recognizes as family members of the service member for purposes of pay and benefits. Except for the case of children ages 21-23, and incapacitated adult children, it has nothing to do with whether the person is actually dependent on the service member.
DITY: Do It Yourself Move. Now called a Personally Procured Move. When you move your own Household Goods instead of letting the military’s contracted movers do it.
DLA: Dislocation Allowance. A payment when you move to cover some of the costs of setting up a new household when you move.

FDS: First Duty Station. The first “permanent” assignment after finishing training.
Geographic Bachelor, or Geobach: Slang for the situation where a service member chooses to live separately from their family because the family does not want to move to the service member’s duty station. Also can be used as a verb: geobaching.

LES: Leave & Earnings Statement. A monthly document given to members of the United States military which explains their pay, allowances, deductions, and allotments. It also includes information about leave, Thrift Savings Plan contribution, and taxes. Similar to a civilian “pay stub.” The LES can be viewed online or downloaded at the MyPay website.

Partial PPM, or Partial DITY: When you have the government-contracted movers move part of your Household Goods, and you move some of it yourself.

Secondary Dependents: Family members who would not normally be considered a military dependent but qualify under special rules. This typically includes parents who are financially dependent on the service member or disabled adult children. Secondary dependency comes with additional benefits that vary based on the type of dependent relationship.

TSP: The Thrift Savings Plan. The federal government’s employer-sponsored, defined contribution retirement plan. Similar to a civilian 401k.
VA: The Department of Veterans Affairs is the government agency that handles benefits for veterans and their families. It also administers some benefits used by currently serving members and their families.
Knowing these terms, and reading more about them, can make military life a lot easier.
And I really mean it – I’m looking for suggestions to add to the list!
