Where did the term S2 originate in reference to military intelligence officers?

S2 is a military intelligence term that originated in the United States Army during World War II. It refers to the intelligence officer on a division or brigade staff, or the intelligence section of such a unit. The term is derived from the French term "deuxième bureau," which was used to refer to the intelligence branch of the French Ministry of War.

In the United States Army, the S2 is responsible for gathering and analyzing intelligence information, and for developing and disseminating intelligence products. The S2 also works closely with other staff sections, such as operations and plans, to ensure that intelligence is integrated into the unit's decision-making process.

The term S2 is also used in other countries, such as Canada and the United Kingdom, to refer to the intelligence officer on a staff.
