Command Destroyer
Command Destroyers (sometimes called "CMDDs", "Jump Destroyers", or "booshers") are Tech 2 destroyers designed for fleet support. They can fit one Command Burst module, but often fit a Command Processor rig to fit a second Command Burst. Further, they have a 2% bonus to the effects of their factions' Command Bursts for each level of 
Command Destroyers, and a 95% reduction in powergrid requirements for Command Bursts. This makes them the only viable sub-cruiser-size hulls to use command bursts.
Their other defining feature is the ability to fit a Micro Jump Field Generator ("MJFG", or "boosh"). This module jumps the Command Destroyer and every ship in a 6km radius 100 km in the direction the Command Destroyer faces as long as they are not scrammed or invulnerable (for example due to gate cloak or tether). MJFGs have a base activiation time of 9 seconds. The jump only happens after this spool-up time, which is reduced by 5% for each level of Command Destroyers and Micro Jump Drive Operation. Command destroyers are the only ships smaller than battlecruisers that can micro-jump, and, moreover, the only ships of any size or class that can take other ships with them in a micro-jump.
On top of these bonuses and abilities, they all have a 50% reduction in Microwarpdrive signature radius bloom. The empire factions' Command Destroyers also have a 4% bonus to resists for their respective faction's tank per level of the relevant T1 destroyer skill. This results in a 20% resist bonus, as a pilot must have their T1 faction destroyer skill at V to sit in the ship in the first place. They also have a 10% damage bonus per level. The Triglavian command destroyer doesn't follow this pattern, having a 10% range and a 20% damage bonus and no resist bonus.
The different Command Destroyer hulls are:
Tactics
The ability to use Command Bursts makes Command Destroyers typical force multipliers because they improve the performance of all ships in the fleet. While Command Bursts are straight foward in their tactical use, the Micro Jump Field Generators lead to more creative tactics. This ranges from booshing ships off from gates or stations to prevent them from jumping or docking, over splitting hostile fleets (expecially logi) to make it easier to kill them, to full booshing doctrines in which a big number of Command destroyers allows to use booshes in short succession to rapidly move around. It is worth to note that while Command Destroyers are usually fleet ships they can also used as solo ships.
Fitting
Command Destroyers almost always fit a Micro Jump Field Generator. Besides that, they can be afterburner or microwarpdrive fitted, sometimes even both. They often fit a warp scrambler; a warp-scrambled ship isn't carried along in a boosh, so by scrambling a ship and then booshing, a Command Destroyer can jump everything immediately nearby away and leave the scrammed target isolated. ECM bursts are another common module. These allow the ship to try to break hostile target locks in case the Command Destroyer or fleet members are scrammed, which would prevent the fleet from booshing out.
The slot layout and bonuses usually force an armor tank for the Pontifex and Magus, and a shield tank for the Stork and Bifrost. In a fleet context you normally fit a buffer tank, while solo fits can have an active tank.
If the Command Destroyer's primary role is to provide Command Burst, a Command Processor rig is usually fitted to allow two active Command Bursts. Some fits even fit two Command Processors to allow three Command Bursts, although these fits usually sacrifice weapons and tank to do so. There are some pilots who use an alt account on a command destroyer as a "backpack", to provide their main ship with command bursts (Skirmish bursts, most commonly) when their main ship is otherwise flying solo.
In a booshing doctrine, some destroyers may not even fit a Command Burst at all, either in favor of additional tank or out of non-necessity.
A defender missile launcher is a popular choice to protect the fleet from bombs.
History
Command Destroyers were introduced in the Frostline expansion (Dec 2015).
The Draugur was introduced in the Invasion Chapter 1 expansion (May 2019), alongside the Nergal and Ikitursa. The Draugur was developed by the Minmatar Republic as a retrofit to the Kikimora, specifically to fight against the invading Triglavian ships.
