Military Monkeys Only

Military Monkeys Only is a BTD6 sub-mode of the Medium Difficulty and is unlocked by beating Standard Medium. As its name suggests player can only use Military based Monkeys (Sniper Monkey, Monkey Sub, Monkey Buccaneer, Monkey Ace, Heli Pilot, Mortar Monkey and Dartling Gunner) and the selected hero is allowed for use.

Tips

 * It is more difficult on maps that have little or no water, because the player will not be able to use Monkey Buccaneers or Monkey Subs (unless they use Portable Lakes). In those cases, the player will only be allowed to place Sniper Monkeys and the hero at the start of the game unless proper Monkey Knowledge is utilized.
 * It is most vital to use Heli-Pilots and Monkey Aces for main defense on maps without water, especially with Apache Dartship and Spectre.
 * Having the Military Conscription and Advanced Logistics Monkey Knowledge will help with this game mode as it makes the Military towers cost less to place.

Strategies

 * On maps with water, you can start with a Monkey Sub. Otherwise, it is recommended to utilize a hero that can be placed at the start such as Quincy.
 * Be sure to get upgrades such as Night Vision Goggles or Crow's Nest to pop camo and, later upgrades such as Hot Shot or Full Metal Jacket to pop leads.
 * Specifically, camo detection is needed for round 24 and lead popping power for round 28, though leaking the first camo Green on round 24 should not be a problem.
 * Reaching round 100 on Military Monkeys Only can be accomplished by using Apache Prime and additional support towers such as Sky Shredder. Farming using Supply Drop and Support Chinook is recommended. On some maps such as Spring Spring and Spice Islands, where water is plentiful, Merchantmen farming is another alternate viable option.
