Only the 3^rd, 7^th, and 8^th Armies are tactical organizations, and because of changing US commitments, only the 3^rd approaches an army in size. The 7^th and 8^th are skeleton formations that would be expanded on mobilization. And even 3^rd Army has only one corps HQ, but the army HQ is needed because of the large numbers of units outside the single corps.

 

US Numbered Corps

 

I Corps (Ft. Lewis, WA) for the Pacific

V Corps (Germany) for Central Europe

III Corps (Ft. Hood, TX) for heavy forces

XVIII Corps (Ft. Bragg, NC) for light forces

 

Of the corps, V is a skeleton HQ that was to be disbanded, but is retained for at least another year.

 

The US Army no longer maintains Corps HQs in its reserve structure.
