FORT SAM HOUSTON, Texas — U.S. Army North commander Lt. Gen. Jeffrey S. Buchanan, who failed a land navigation course as a lieutenant, mistakenly reported for duty today at U.S. Army South, sources confirmed.

His confusion may have occurred because U.S. Army North (ARNORTH) is located on the same installation — Fort Sam Houston — as U.S. Army South (ARSOUTH). Or it could be that officers of all ranks can’t tell left from right, or north from south.

Maj. Gen. Mark R. Stammer, the commander of ARSOUTH, was reportedly shocked to see a lieutenant general standing outside his office asking the chief of staff for the latest weekly battle rhythm, updates on that SIPRNet issue, and whether anyone had restocked toilet paper in the “little general’s latrine.”
