All Primary Monkeys in radius get more range, pierce and projectile speed.
~ BTD6 description

Primary Training is the third upgrade of Path 1 for the Monkey Village in BTD6. It allows all Primary towers within its radius to be given bonus +1 pierce, +10% range, and +15% (?) projectile speed. It costs $680 on Easy, $800 on Medium, $865 on Hard, and $960 on Impoppable.


  • This upgrade tends to benefit Tack Shooters the best, since they have short range and low pierce. In addition, tacks flying faster can improve the Tack Shooters' accuracy.


Primary Training is a rather anomaly upgrade for the Monkey Village. At a cost less than its preceding upgrade, Jungle Drums ($1500 compared to $800), Primary Training adds additional benefits to only Primary Monkeys on top of the usual 15% attack speed bonus from the preceding upgrade and 10% range from the default Monkey Village stat bonuses. That means that only Dart Monkeys, Boomerang Monkeys, Bomb Shooters, Tack Shooters, Ice Monkeys, and Glue Gunners will benefit from the Primary Training upgrade bonuses on top of the pre-existing bonuses granted by the precedessor upgrade. All other nearby towers will benefit only from the stat bonuses granted by Jungle Drums.

Much of the benefits of Primary Training come from exclusively benefiting the Primary Monkeys class, which generally are weak on their own. Range bonus benefits will help greatly on small-range towers such as Ice Monkeys and Tack Shooters, allowing them to deal wider area-of-effect attacks at bloons. Pierce bonus benefits are exceptionally good on all Primary Monkeys – Glue Gunners such as MOAB Glue and Bloon Liquefier benefit greatly by affecting many more bloons or blimps at once, while Tack Shooters can shred many more bloons at once without repeatingly reaching their pop limits. Increased projectile speed benefits are not nearly as useful compared to the other two, but they are incredibly handy at chasing out fast bloons, especially for Bomb Shooters or Upper Path 3 Ice Monkeys.



  • This is the only Tier-3 upgrade in BTD6 that is always cheaper than its base tower (since Signal Flare can be more expensive than their respective base towers with "Military Conscription" Monkey Knowledge)
  • The Primary Training upgrade alone requires less XP to unlock than the Radar Scanner upgrade alone (2500 XP).
