Something I found with the Shields
The 12 shields in order in the game's Dossier
Shepard, Hazard, Deadeye, Avenger, Sacred, Phoenix, Talon, Rebel, Fang, Prime, Marshal, Chieftain
First letter of each
SHDASPTRFPMC
Seperating them into 3's
SHD, ASP, TRF, PMC
SHD = Strategic Homeland Division (The Division)
ASP = Armament Systems and Procedures or AeroSpace (Guess)
TRF = Tactical Response Force (Guess)
PMC = Private Military Contractors (like the LMB)
I'm thinking Aerospace for ASP because there is a lot of aerospace companies in DC and the Smithsonian National Air and Space Museum is on the Division 2's DC map.
I was gonna solve/ see if there is more to this by myself but I've been busy with Uni and thought it'd be kool to share anyways.
