The Army has announced several promotions and changes among the top positions at the Corps of Engineers. The most-senior Corps of Engineers change among a group of 17 Army and Army Reserve personnel announcements on June 7 is the promotion of Brig. Gen. Kirk E. Gibbs to be deputy commanding general for military and international operations.  

Gibbs is being elevated from his current position as commander of the Corps’ Pacific Ocean Division, based at Fort Shafter, Hawaii.

In his new post, Gibbs succeeds Maj. Gen. Kimberly M. Colloton as deputy commanding general for military and international operations. Colloton on April 3 was named deputy chief of the Corps and its deputy commanding general, the Corps' number-two position. 

The latest announcement also includes the naming of Brig. Gen. William. C. Hannan Jr. to be the commanding general of the Corps Northwestern Division, based in Portland, Ore. 

Hannan will move from his present post as as head of the Corps Transatlantic Division, based in Winchester, Va. The current Northwestern Division commander, Brig. Gen. Geoffrey R. Van Epps, will become deputy commanding general of III Corps, in Fort Cavazos, Texas. 

The moves typically take effect at change of command ceremonies, held several months after the announcements.
