Sentinel Captain

Description
Sentinel Captains look much like Onyx Sentinels, however there are some differences. For one thing, instead of three booms surrounding the central spherical eye, there are four, creating an odd sort of 'X' if looked at from the front. From the sides, the four booms curve back, retaining the Sentinels' cylindrical form. Attached to each of the four metal booms is attached a small beam weapon, its strength somewhere in between the Sentinel Beam and the Colossus Laser. The main shield generator is in the core of the central eye itself, and is constantly seen; a sphere of golden light.

Defensive Systems
The Sentinel Captain's shield, as said before, is constantly active and visible, portraying itself as a sphere of golden light surrounding the Sentinel Captain itself. This shield is very durable, and can sustain up to 5 shots from a Scorpion Tank before failing, also, the metal from which the Sentinel Captain is made seems to be a much weaker, yet still extremely strong, form of the alloy used in Monitor casings.

Offensive Systems
The four beam cannons attached to each of the Sentinel Captain's booms, are extremely powerful, being able to blast through and burn nearly anything. It has been speculated by ONI after the information of Installation-07 was sent to earth, that the beams used by the Sentinel Captains could possibly be highly concentrated forms of the Colossus Beams. However, since the Colossus Beam is able to do much more damage in its non-concentrated form, this speculation may be debated on.

Known Members
The only known Sentinel Captains are 64-Vigilence, 512-Redemption, and 4096-Purification. Whether or not there were Sentinel Captains on the other Installations that were not seen or heard about, it is not certain.

Intelligence
Surprisingly enough, Sentinel Captains could be said to have "Personality". They are known to actually speak for themselves, albeit in monotone, and command other Sentinels with verbal commands. They are not mindless drones, but they are still designed to obey the Monitor at all costs. If the Sentinel Captain does attempt to disobey the Monitor, the Monitor has a system at its disposal that will immediately and permanently shut down the Sentinel Captain. It should be noted that this is similar to the neural implants that UNSC Navy Captains have, allowing them to destroy A.I.s.
