Support Chinook (BTD5)

"Abilities: drops med and cash crates, or can pick up and reposition most towers."

- Bloons TD 5 Mobile description

Support Chinook is the final upgrade on the second path for the Heli Pilot in BTD5. It gives the Heli Pilot abilities to pick up and move towers or drop medical and cash crates. In BTD5, this is the only way to obtain additional lives in Deflation Mode without buying Healthy Bananas. It costs $15,000 on Medium in BTD5.

Abilities
The Support Chinook has two different abilities available, more than almost all towers with abilities. One of these abilities alternates between giving cash or lives, while the other ability can reposition most types of towers to a different location.

Note: As there are no official names for the two different abilities, unofficial names are assigned to each of the two abilities.

Supply Crate Ability
Every Support Chinook's Crate Ability has two different crates that can be spawned: a Cash Crate and a Health Crate.

Every Support Chinook crate will guarantee start with cash, then the second one with lives, and the process repeats. Every cash crate will drop a random value between $1,500 and $2,000 (BTD5), while every med crate will drop a random value between 50 and 75 lives. The Cash Crate/Health Crate Ability both have the same cooldown of 60 seconds.

In BTD5 Mobile, the ability to dropping a cash crate becomes immediately available.

Redeploy Ability
The Redeploy Ability, also referred to as the Tower-Moving Ability, is the ability that allows the Support Chinook to move towers to a new location. Upon activation, the screen will pop up with a menu for moving a tower. Most towers are able to be moved, but there are a number of towers that cannot be moved. Upon moving the selected movable tower to a new spot, the Support Chinook will move (even when set to Lock in Place) towards the selected tower to reposition that tower to a new spot.

The list of towers that cannot be moved include:
 * All Banana Farms
 * All Monkey Villages
 * Temples of the Monkey God / Sun Temples
 * The True Sun God
 * Aircraft Carrier and Carrier Flagship
 * All Monkey Ace landing bases

BTD5 Mobile Bugs

 * If a player moves a Sun God before it becomes a TOTMG the player technically can move a TOTMG but a Sun God ios being moved on top of a TOTMG.
 * However, this has been fixed in the 2.17 update, unallowing towers to upgrade before picked up by the Heli Pilot.
 * When a player picks up a tower the player can place another tower where the other was being placed.
 * If a player tries to move a Sentry out of the Engineer's range, it crashes the game.

Update History (Bloons TD Battles Mobile)

 * 4.3.1

It is now no longer possible to stack towers on top of other towers with Support Chinook.

Trivia

 * Support Chinook is the only upgrade in BTD5 that gives the tower two Special Abilities.
 * The Support Chinook is based on the real Boeing-Vertol CH-47.
 * If players are trying to pick up a Monkey Village, Banana Farm, or Temple of The Monkey God, it will not pick it up and use the pick up ability so the player can still pick up other towers.
 * One of the abilities this upgrade unlocks gives lives in Deflation Mode, which is probably unintentional.
 * If the Heli-Pilots are flying at the very end of the track and 1/1 Ice Towers are spammed on the rest of the track, the bloons will take a very long time to reach the end, and the cash/life crate dropping ability can be abused to gain lots of lives, more notably in Deflation Mode.
 * In Bloons TD Battles Mobile and Bloons Monkey City Mobile, if players lose lives but uses life crates to regain them to get it to the amount of lives the player started with, the player will still not receive the NLL bonus (7 or 2).
 * In-game, the pilot is still visible. This is not the case in BTD6.
