How can I get a copy of my ULLS-A PID record?

"would help" but it's not on the list of requirements:

Formal Training Waiver packets will include:
Signed DA Form 4187 to include para/lin, duty title, UIC justification, unit POC info, and both company and battalion commander signatures.
Current copy of ERB/SRB to validate ASVAB/AFCT line scores.
DD Form 2808 most current to validate PULHES and color vision.
State Surgeon Waiver (NG Only) stating Soldier is capable of performing duties with associated MOS required when servicemember’s PULHES does not meet criteria specified in DA Pam 611-21.
Personnel Qualification Record (PQR) current copy of PQR (NG only).

Documented Aviation Experience
Previous Army Aviation ASI/MOS producing certificates (DA Form 1059 or Diploma or in your case the USMC school cert and MOS order)
All previous NCOES DA Form 1059s

A & P License

DA 7817 Aviation Maintainer Record if applicable to verify designated maintenance level for the following MOSs: 15B, 15D, 15F, 15N, 15Y, 15H, 15E, 15G, 15M, 15R, 15T, 15U, 15L, 15K.
Job Book/ACN (minimum of one year experience with aircraft specific to requested MOS)

DD Form 214 required for any current active duty servicemember with a break in service, all National Guard, and Army Reserve Soldiers.

Looks like the ULLS record would be needed in lieu of a DA 7817. Any 92A and probably a maint chief should be able to access ULLS, also looks like you need to be assigned back into a 15T duty position and have that AV BN submit this packet.
