There are more than 20 trades in the Army, and training is different for each one. Generally speaking, all involve an initial trade training course that begins once AARC Training is complete. This course gives you the essential skills and knowledge you need to be able to perform your duties, and provides you with the history, traditions and customs of your unit. Throughout your training, you'll log your competencies for trade tasks, on-the-job training, trade courses and experience.
