The Basic Officer Leader Course (BOLC) is a two-phased training course designed to commission officers and prepare them for service in the United States Army. Prospective officers complete Phase I (BOLC A) as either a cadet (United States Military Academy or Reserve Officers' Training Corps) or an officer candidate (Officer Candidate School (United States Army)) before continuing on to BOLC B as Second Lieutenants. If BOLC B is not completed within two years of commissioning, 2LTs will be administratively separated from the service unless there are extenuating circumstances. This a progressive model designed to produce US Army officers with leadership skills, small unit tactics and certain branch-specific capabilities.
