There are different levels of recruit training, and each corps or major unit has their own training program. Upon completing tironut, non-combat recruits are certified as Rifleman 02. Combat recruits must complete Rifleman 03 basic training. Generally, infantry-specific training ranges from Rifleman 05 (combat engineering) to Rifleman 07 (infantry and combat engineers sappers, upon completion of advanced infantry training), whereas armored or artillery corps complete Rifleman 03 training. Elite units such as Sayeret Matkal do not complete a standard basic training course for a rifleman certification and have their own extended training courses which last over one year.
