The unit MTP and METL will dictate tactical scenarios, task organization, and weapons mix. The commander assesses training for the USR by developing a training level or T-level. The primary purpose of the T-level is to show the unit's current ability to perform its assigned wartime missions. He considers all available factual data in making the determination. The training level determines how much time is needed to train the unit to do its mission essential tasks.
Many factors affect the unit's T-level.
AR 220-1 states that proficiency is measured in terms of the unit's demonstrated ability to do its mission essential tasks. The unit also must perform enabling tasks not specified in the METL but necessary for performance of mission essential tasks. An example of an enabling task is crew gunnery. Proficiency is judged on performance of tasks to standard. However, proper reporting of helicopter gunnery problems and successes on the unit status report is also important.
