Military Monkeys

Military Monkeys are the second category of towers in BTD6. They are unlocked at Level 7, after all Primary Monkeys are unlocked. The common traits shared by all Military Monkeys is that they all feature a way to make use of their terrain advantage in some way shape or form, whether it be long-ranged attacks, special terrain placement, specialized mobility, or a combination of the three. Military Monkeys are identified by a moderate green background, resembling the militaristic theme of Military Monkeys.

There are 7 Military Monkeys in the game:

Military Monkeys affect the sacrifice categories for Sun Temple and True Sun God (and by extent, Avatar of the Vengeful Monkey too). Military Monkeys possess no class-exclusive benefits from any tower, although the two only water-based towers (Monkey Subs and Monkey Buccaneers) can benefit from Carrier Flagship or Admiral Brickell if placed on water, and likewise Carrier Flagship can buff Monkey Aces regardless of where the landing pads are placed. Military Monkeys can also be placed on the green emblem on the map Encrypted. On Military Monkeys Only, a sub-mode on Medium Difficulty, the only available towers to place are all the Military Monkeys and the selected Hero.

Introduction to the Military Monkeys

 * Sniper Monkey: The Sniper Monkey wields a rifle that can shoot bloons across any distance provided that its vision is not obscured by any obstacles. Rifle shots deal a high amount of damage per shot, but fire somewhat slowly and only hit one bloon at a time. It can be upgraded to improve its damage and attack speed, as well as improve any of its special support functionalities. It can affect many more bloons per shot with special upgrades. Giving the Sniper Monkey with Night Vision Goggles allows it to detect camos.
 * Monkey Sub: The aquatic submarine is operated by a monkey sailor, shooting darts through the submarine's gun. It shoots faster than a Dart Monkey and its darts can naturally home at bloons. The Monkey Sub comes with many advanced upgrades that each provide unique roles at dealing with various bloon types. Monkey Subs and their upgrades tend to have an overall moderate amount of all basic stats: moderate range, moderate pierce, moderate attack speed, moderate damage, and a moderate price. One special upgrade, Advanced Intel, however, allows the Monkey Sub to gain a substantially high amount of range. Camo detection is available for the Monkey Sub as an upgrade, directly or indirectly.
 * Monkey Buccaneer: The Monkey Buccaneer shoots heavy darts at bloons with its dual cannons, popping up to 4 bloons per shot. It can shoot both forwards and backwards, and it possesses high range. Its upgrades are generally low in price range, as many of its higher-tier upgrades are quite inexpensive compared to other towers. Monkey Buccaneers can be upgraded to attack faster, increase its weapon arsenal, or act in a support role. Camo detection is available for the Monkey Buccaneer by giving it Crow's Nest.
 * Monkey Ace: Flying in the air in a fixed path around its runway, the Monkey Ace continually shoots 8 darts vertically, horizontally, and diagonally every few seconds. It has limited mobility but its attacks can ignore any obstacle on screen. It can be upgraded to shoot more darts per second, drop bombs, or deploy many other aerial attacks. Camo detection is available for the Monkey Ace with the Spy Plane upgrade.
 * Heli Pilot: Riding in a highly mobile helicopter, the Heli Pilot can be moved around anywhere on screen to shoot twin darts at bloons at a fast speed. The mobility of the Heli Pilot can be increased with upgrades, and comes with many offensive or supportive upgrades for helping the defense. It can detect Camo Bloons by adding IFR.
 * Mortar Monkey: The heavy artillery operated by the Mortar Monkey fires out mortar shells that explode onto any location on screen. This heavy artillery cannon can attack anywhere on screen, pointing at a specific location and narrowing the site of detonation according to its target reticle. The target reticle can be adjusted manually. Like all explosives, the Mortar Monkey packs with high pierce per shot. Its explosives can be improved greatly with upgrades, improving its overall damage or applying secondary effects to each explosion. Signal Flare allows it to both detect Camo Bloons and strip the camo property off bloons.
 * Dartling Gunner: Wielding a minigun, the powerful Dartling Gunner shoots darts at very quick speeds. The Dartling Gunner's aim is manually adjustable by user interaction with the screen, or it can be locked to point at a specific location. Like the Sniper Monkey, the Dartling Gunner has unlimited range but is limited by obstacles present on the map. It has among the most expensive upgrades overall, but it comes with many upgrades that modify its long-ranged manually aimed attacks to optimize its high DPS potential. Advanced Targeting allows the Dartling Gunner to detect Camo Bloons.

Summary
Military Monkeys are more flexible than Primary Monkeys and possess decent high-range options, but are usually more expensive than Primary Monkeys and generally have less synergy potential than Magic Monkeys. Overall, Military Monkeys have a moderate amount of versatility for a rather decent price.

Tips

 * Military Monkeys can benefit from the Monkey Knowledge Point "Military Conscription". With this MK, the first Military Monkey placed will be 33% cheaper.
 * Since the majority of Military Monkeys in the game have long range, it is worth optimizing them on areas where they cover the most track while attacking.
 * For Sniper Monkeys and Dartling Gunners, it is a good idea to place them on High Ground to make the most of their infinite range potential.
 * For Monkey Buccaneers, placing it along a good straightaway is the best approach to making the most of its attacks. Placing a Buccaneer in a location where it can attack from both sides can increase its damage output by up to twice than normal.
 * For Monkey Subs, it is recommended to let a Monkey Sub attack with as much bloon track coverage as possible, so its attacks can gain more opportunity to attack bloons within further range. All its attacks benefit from doing so: dart attacks will always home on bloons, so more bloon track would benefit those attacks; the Ballistic Missile attacks any any bloon within range (or any bloon on screen with 2-3-0), which benefits for similar reasons; Submerge Subs decamo more reliably; and Reactors gain maximum coverage for damage.
 * For all Military Monkeys except water-based towers, their long-ranged potential means they do not have to be placed in strategically optimal locations to make the most of their attacks, ignoring the presence of Line of Sight issues.

Trivia

 * Military Monkeys are the only category of BTD6 towers where there two towers have been added in later updates.
