IMCOM, or U.S. Army Installation Management Command, is responsible for the day-to-day operations of 104 U.S. Army installations worldwide.

Quick Scoop

  • If by “ID” you mean installations, the current public Army source I found says IMCOM manages 104 installations.
  • IMCOM is part of the Army, not the DoD at large, so it is usually described as an Army command within the Department of the Army.
  • One public IMCOM page also shows the command’s organization and mission structure, which supports that it is an Army-level command focused on installation support.

Plain Answer

The best direct answer is: IMCOM oversees 104 Army installations.

Note on wording

Your question says “How many ID under IMCOM are in DoD Army,” which is a bit unclear. If you meant:

  • installations , the answer is 104.
  • directorates, IDs, or subordinate organizations , the count depends on which specific category you mean, and that needs a narrower definition.

TL;DR: IMCOM handles 104 Army installations.
