There are several references for corrective training. AR 27-10 and AR 600-20 provide information on corrective training. AR 600-20 para 4-6b, states:
b. One of the most effective administrative corrective measures is extra training or instruction (including on-the-spot correction). For example, if Soldiers appear in an improper uniform, they are required to correct it immediately; if they do not maintain their housing area properly, they must correct the deficiency in a timely manner. If Soldiers have training deficiencies, they will be required to take extra training or instruction in subjects directly related to the shortcoming.
(1) The training, instruction, or correction given to a Soldier to correct deficiencies must be directly related to the deficiency. It must be oriented to improving the Soldier’s performance in his or her problem area. Corrective measures may be taken after normal duty hours. Such measures assume the nature of training or instruction, not punishment. Corrective training should continue only until the training deficiency is overcome. Authority to use it is part of the inherent powers of command.
