What is a DD Form 3120?
DD Form 3120 is the DoD Government Travel Charge Card (GTCC) Statement of Understanding. Military members and civilian employees sign it before they receive a GTCC, which they must use to pay for authorized travel costs like lodging, meals, and airfare. Signing this form confirms the cardholder understands their duties, including paying the bill on time and following travel rules. This step protects both the employee and government funds from misuse.

When is a DD Form 3120 due?
There's no fixed calendar date. You must sign a new DD Form 3120 when you arrive at a new duty assignment, before your travel card is issued or used, and again every three years along with your GTCC refresher training. Timing depends on your assignment and card renewal cycle, not a set date.

When is a DD Form 3120 not required?
You only need a new statement when you arrive at a new duty assignment or when three years have passed since your last one. Outside those triggers, no fresh DD Form 3120 is due. Note that an approved exemption from carrying the GTCC itself doesn't remove the requirement to complete the statement of understanding when a new card is issued.
