More rules for NGB Form 594-4
Under 1, you understand that enlistment for the Split Training Option provides that you must enter on Initial Active Duty for Training (IADT) to undergo the Army basic training (BT) program at an active military installation.
Under 1, if you fail to successfully complete the BT program you will be discharged from the ARNG and Reserve of the Army.
Under 1, upon successful completion of the BT program you will be released from IADT and permitted to return to civilian status, and you will then immediately commence training with your assigned ARNG unit in a paid drill status. During this period you are not required to attend Annual Training (AT) with your unit, but you may volunteer to attend AT and may do so if authorized by your unit commander.
Under 1, within one year of the last day of your separation from IADT (after successful completion of BT), you will be required to again enter on IADT to successfully complete Advance Individual Training (AIT) resulting in qualification in a Military Occupational Specialty in which you are to be trained.
Under 1, if for any reason you are unable to successfully complete AIT during the period for which you were ordered on IADT, you agree to remain on IADT for such additional period as is required to become qualified in your selected MOS, or to accept training in an alternate MOS, if offered, and remain on IADT for such additional period as may be required to complete such training and become qualified in the alternate MOS.
Under 2, you understand that BT and AIT are considered IADT and the minimum period or time you must spend on IADT is 12 weeks.
Under 3, you understand that you may not voluntarily change your selected MOS after the reservation for entry on the AIT portion of IADT has been confirmed.
Under 4, you understand that under current provisions of law you will not satisfy your military service obligation unless you complete eight years of satisfactory service as a member of the ARNG and Reserve of the Army, and, during such service, complete 12 consecutive weeks of active duty for training with an Armed Force (even though you complete all required training following enlistment in the Split Training Option).
Disclosure is voluntary; however, if not provided you will not be accepted for this enlistment option in the Army National Guard.
The original will be maintained in the Soldiers Official Military Personnel File or electronically filed in a DoD approved system, and a copy will be maintained by the MILPO for state records.
Common questions about NGB Form 594-4
Is there a deadline?

What am I certifying when I sign?
