AOR1/Desert Digital Pattern:
These are recently (as of 2022) issued to US Navy EOD personnel (source: https://www.facebook.com/groups/1800973036588888/posts/5988823021137181?comment_id=5989861991033284, https://featurekreep.blogspot.com/2017/04/ebay-find-t3-tora-bora-pack.html). There are no tags or markings.
Tri-zip design was originally created by Mystery Ranch to allow the pack to be opened more widely for easier access to contents (source: https://www.carryology.com/bags/best-backpacks-reviewed/carry-geeking-tri-zips/).

Hypalon reinforcement material on the bottom.

Plastic Hardware:
Most buckles are entirely sterile, but there are some 10/2018 date codes on some plastic parts, indicating this pack was likely made in late 2018 – 2019.
Lid:
Holes for antennae or hydration tubing? 
Lid cannot be detached from the pack.
Back:
Metal frame similar to ALICE pack design. This was a military-only offering from T3 until recently (~2021) (source: https://www.facebook.com/groups/1800973036588888/posts/5988823021137181/?comment_id=5989861991033284&reply_comment_id=5990038761015607). The combat controller version of this rucksack is distinguished by the metal frame (source: https://haguesolutions.org/whats-in-my-pack-winter-21-22/).
