What is the current process for the Tattoo Validation memorandum?

"Tattoo ETP - UPDATED HQDA G-1 TATTOO GUIDANCE (For ALL Applicants to include Sister Services):

AR 670-1, dated 25 MAY 2017, no longer provides a provision for grandfathering tattoos. The grandfathering provision was provided in the March 2014 iteration of AR 670-1, and provided ample time for Soldiers and CDRs to documented eligible tattoos in the Soldier's iPERMS. HQDA G-1 will NO LONGER accept tattoo ETPs (from Army Applicants) for WO appointment unless the procedures outlined in AR 670-1 par3-3f are followed. Soldier MUST provide separation board proceedings indicating the CDR retained the Soldier along with a Tattoo ETP Request (found under the "Downloads" tab). Additionally, as part of the WO application checklist (under downloads tab), the applicant's servicing Battalion S-1/S-1 NCO or PSD/MPD Supervisor must verify that the CDR has completed a tattoo verification, been found in compliance with AR 670-1 (dated 25 MAY 2017) and that all tattoos are properly documented in iPERMS. If a Soldier is in compliance with the tattoo guidance in AR 670-1 Para 3-3 (dated 25 MAY 2017) and has verified with their BN S-1 (indicated on the application checklist) that their "non-compliance" tattoos below the wrists (on the hands) and/or above the neck line (on head/face/inside mouth) were properly uploaded into iPERMS (ICW the March 2014 version of AR 670-1, i.e. grandfathered) they DO NOT require a tattoo ETP."

There is no such thing as being grandfathered when it comes to tattoos when switching components. Refer to AR 670-1. You will need an ETP from DA G-1

Ah, sxxt!
