Army- Because of Confederacy's diverse spiecies and technologies, each members are allowed to keep their own army, and are encouraged to do so. But main bulk of Conferderacy's army are the droids that are massively manufactured by the forge worlds and foundry worlds. Although not as smart as a normal trained human being, they are capable of fighting and completing their objectives. Even amongst the droids there are obvious difference between the programs. The ranks and function of droids can be told by color of their shoulder, but some detachments of droids are colored and equipped to fit the certain kinds of enviroments (Like extreme desert or extrme artic etc.) Most of the battle droids need a special command broadcast that is broadcasted by a ship or command centre of some sort. This broadcast band is known to impossible to crakc and is changed every one minute. No one has ever figured out what frequency the droid is recieving every minute, no one every hacked into the system, and even the command ship sometimes doesn't know what frequency they are broadcasting on. Not all droids need the command broadcast, a new design of droid named B-3 Super Battle Droids need not to recieve the signal to operate. Of course the droids are not the all of C.I.S.'s army. It also includes bionic army, like soldiers of Amarr, Genosis, Gallentre and such, but they are considered minor. If a memeber finds a better tehnology the whole Confederacy shares it and if wish to re-equip themselves with it.

IG 100 Magna Guard- These are the Ultimate model of droid there is in the Confederacy. Custom made and extremely limited in number, it's number is un-known but proved there are less than 20 of it. Unlike the mindless droids, these are equipped with sophisticated personal AI. They are capable of learning faster than the human and more stronger than most of bionic speicies. They are equipped with numerous weapons and feature that makes them almost invincible in the battle field. These are very resilient even for a non-organic. Unfortunately there are no current plans to make any more of these due to a fact, that couple years ago manufacturing just 10 of them drove Trade Federation almost to the bankruptcy. None of the these droids have been destoryed even though they have been in numerous battles, they are considered near invincible, but not exactly invincible.
