Correction

A July 2 story about a military smoking ban should have said the nonprofit, independent Institute of Medicine was responsible for the smoking study.

A July 2 story about a court-martial stemming from a brawl in South Korea misstated the actions taken against Sgt. Markease Joyner and Spc. Markelle Joyner. The brothers were detained and questioned after the incident but were not arrested. They are each charged with two counts of aggravated assault and one count of providing a false official statement. Their first names were also misspelled.
