1-32. Key to effective unit training is the commander’s involvement and presence in planning, preparing, executing, and assessing unit training to standard. Commanders ensure MTP standards are met during all training. If a squad, platoon, or company fails to meet established standards for identified METL tasks, the unit must retrain until the tasks are performed to standard. Training to standard on METL tasks is more important than completion of an event such as an EXEVAL. Focus on sustaining METL proficiency—this is the critical factor commanders must adhere to when training small units.
