Summary

Story summary

The U.S. Army removed Lt. Gen. Charles Costanza as V Corps commander because sources cited conduct and an alcohol problem, not Defense Secretary Pete Hegseth.
Brig. Gen. John B. Mountford became V Corps commander, with Maj. Gen. Thomas Feltey set to take over in October.
The removal joins two dozen officer dismissals and follows Donald Trump’s 5,000-troop plan after a brigade deployment to Poland had not arrived by late July.
