From the desk of Project Blue Book Operations Director [REDACTED]:
Overview
Project Blue Book is divided into 3 separate branches, the Xeno Defense Bureau (XDB), the Scientific Research Bureau (SRB), and the Engineering and Manufacturing Bureau (EMB). All operations that involve Blue Book are conducted by at least one of these branches. Blue Books modus operandi as an organization is that while battles are fought in the field, wars are won in the lab. The principles taught by the horrors of World War 2 have shown that the application of force AND technology are vital to victory. To that end, the number 1 priority of all Blue Book field agents is the retrieval of intact field samples.
The second major principle of Blue Book is the belief in the application of force, wars are not won through mercy, and they are not won through holding back. Blue Book supports the proliferation and use of all weapons and operates on a doctrine of massive and superior firepower.
Xeno Defense Bureau
Composed of volunteer forces culled from the various Blue Book member states armed forces, the Xeno Defense Bureau serves as the military apparatus of Project Blue Book.
The XDB is further divided into Blue Book Intelligence (BBI), Blue Book Land Command (BBLC), Blue Book Air Command (BBAC) Blue Book Space Command (BBSC), and Blue Book Naval Command (BBNC).
The "Sword and Shield" of humanity, the XDB is the first on the ground in the event of combat. With a standing policy of threat elimination and resource acquisition, the XDB sees combat as a small part of the job that Blue Book holds.
Scientific Research Bureau
Composed of recruited scientists from across the globe, The Scientific Research Bureau is the Scientific arm of Project Blue Book.
The SRB is the beating heart of Blue Book. Encounters and combat against T-001 have shown that in order to stand against foreign invaders, we must not only conquer them on the field we must dominate them in the lab. Reverse Engineering the tools and weapons used against us and turning them against their masters is what has allowed us victory time and time again.
Engineering and Manufacturing Bureau
Composed of engineers, architects, and scientists recruited globally, the Engineering and Manufacturing Bureau holds the responsibility of crafting and fielding all equipment in use by Blue Book.
Early on it was determined that for Blue Book to function to its maximum potential, they could not afford to outsource the various pieces of equipment, this became more and more true as Blue Books standard arms were supplemented by first captured and then human-made variants of ET technology. Outsourcing Blue Books mag sails alone could allow for a substantial breach in security let alone the more delicate equipment Blue Book makes use of.
At this point in time, over 85% of Blue Books arms and equipment are made in-house by the EMB.
