If the date of rank remains the same, the officer will have less time on active-duty, compared to his peers, to gain experience before the next promotion board. Hopefully, an AGR officer who has transitioned from TPU can share their experience.How is date of rank and promotion timeline affected when transitioning from Reserve TPU to AGR?2015-10-22T10:40:33-04:00LTC Private RallyPoint Member1057836<div class="images-v2-count-0"></div>I can't find any information that explains the impact of the transition on an officer's date of rank and subsequent promotion timeline.

Date of rank remains the same, so long as there was not a break in service. Thus, if a TPU officer transitions to AGR their DOR remains the same. Perhaps, this info will also be helpful to someone else in the future.Response by LTC Private RallyPoint Member made Oct 22 at 2015 10:58 AM2015-10-22T10:58:57-04:002015-10-22T10:58:57-04:00LTC Private RallyPoint Member1058623<div class="images-v2-count-0"></div><a class="dark-link bold-link" role="profile-hover" data-qtip-container="body" data-id="771933" data-source-page-controller="question_response_contents" href="/profiles/771933-49a-operations-research-systems-analysis-usarc">LTC Private RallyPoint Member</a> nothing changed but the months of federal active service. They calculate how many days were equivalent to AC time and that is used only to convert you over to the AC retirement. Though you get 20 year letter and can retire with reserve pension as well.Response by LTC Private RallyPoint Member made Oct 22 at 2015 2:39 PM2015-10-22T14:39:06-04:002015-10-22T14:39:06-04:00LTC Private RallyPoint Member1097766<div class="images-v2-count-0"></div>What's particularly different in the transition is that your TPU time is calculated and you are provided a Basic Active Service Date, which we typically didn't have in TPU status -- or it was the same as our PEBD. The BASD provides you the new date from which you calculate when you're eligible for a 20-year AD retirement. It considers deployments, mobilizations, ATs, some ADT, but not battle assemblies, membership points, or correspondence credits.Response by LTC Private RallyPoint Member made Nov 9 at 2015 4:37 PM2015-11-09T16:37:34-05:002015-11-09T16:37:34-05:002015-10-22T10:40:33-04:00
