D-Series Power Armour

"Hell, this thing was around before the SPARTANs even came into existence. Humanity must be really hard-pressed to be using such antiques."-Unidentified Marine during the Battle of SardiorThe D-Series Powered armour is a line of human made assault armour, and humanity's first attempt at making powered armour. Commissioned by the Office of Naval Intelligence for the use of the SPARTAN-IIs, the D-Series was ultimately scrapped in favour of Project MJOLNIR. However, several models were used by UNSC marines during the Battle of Sardior, and a second model has recently been made by Misriah for the civilian market.
== Specifications ==
"Well, this thing doesn't have any energy shielding, and it's bulky and heavy. Two things to be said for it though: One, you don't need to be a godlike super soldier to wear it. Hydraulics take care of themselves. Two, despite the fact that it doesn't have any energy shielding, its thick plates make it extremely hard for anything other than a rocket launcher to deal a one shot kill. You could fire away at this thing with a SAW and it wouldn't do that much damage".
-ONI operative when considering introducing the D-Series to the Marine Corps.
=== Power Source ===
Unlike Mjolnir's miniscule fusion generator, the D-Series lacks a constant power source, limiting it's combat potential. This is unfortunate, as the armour requires a large supply of power for the immense amount of hydraulics. The armour can be moved and worn without the power source, but it is much slower, more cumbersome, and cannot access many systems, with all but vital ones being disabled. In order to combat this problem, Misriah created the fusion core, what was essentially a nuclear battery. This new power source did not produce infinite power, rather, instead pushing it's stored energy into the suit, giving roughly ten hours worth of power. This allowed short skirmishes to be fought easily, but was unpractical for longer scale campaigns, as each suit of armour had to carry at least 20 fusion cores around with them. This impracticality was what led ONI to discarding the D-Series, turning their interest to Project MJOLNIR instead. 
=== HUD System ===
For it's time, the D-Series was incredibly advanced with HUD, being in a constant VISR mode, along with motion trackers and a targeting reticule, permitting instant threat location, with a TACMAP uplink that allowed for easy location of rally points. Ammunition was displayed in the bottom right corner. Another meter displayed armour integrity, along with user vitality. However, all of this had a drawback, with this targeting system requiring a constant power source, and was the reason why the fusion core was chosen over alternative power sources. Another drawback of this was that it was too complex, with ONI preferring the simpler HUD of Mjolnir. 
=== Protective Measures ===
Due to it's early development, the D-Series lacked energy shielding, with no overt protection against plasma weaponry. However, what it lacked in energy shielding, it made up for in the thickness of it's plating, with bullets below 50 calibre likely ricocheting off, thus providing superior protection against the ballistic arms used by humans, which was what it was developed for. A later model possessed an electromagnetic field that disrupted plasma weaponry. The armour plating was manufactured from A-grade titanium alloy, thus allowing the deflection of said ballistics.
=== Hydraulics ===
One similarity that the D-Series possessed to Mjolnir was simple: Strength amplifying hydraulics. These hydraulics, when connected to a power source, permitted the easy moving of the armour. This was one advantage of the D-Series to project Mjolnir, as a user did not need to be augmented to use the armour safely. These hydraulics vastly amplified a users physical strength, allowing them to wield heavier weapons such as chainguns as a main form of attack. A punch from a hydraulic amplified fist was enough to knock a Sangheili out cold, and crush a human skull.
== Models ==
=== D-42 Model ===
The D-42 was the first powered armour produced by Misriah, and was the most common existing model on the market postwar. It was the most cheaply built, and thus the most wildly distributed, of the D-Series. Like later models, it features a head mounted flashlight, along with with lesser (Though still formidable) hydraulics. The armour possesses a ventilation system for hazardous environments, but unlike later models, has no internal oxygen supply, preventing EVA and other operations in airless locales. Lighter plates allow for the easy injection of medkits. The operator enters the armour from the back of the suit. Like the D-64, the D-42 has recently entered the civilian market.

=== D-64 Model ===
The D-64 was the second model of armour produced by Misriah, but is far less common than the weaker D-42 model. Intended for use by the UNSC Marine Corps, this armour was only sent to a few battlefields before the war ended. Similar to its predecessor, the D-64 has a helmet-mounted flashlight, but the beam produced is far narrower for the purpose of energy efficiency. The model has the potential to extract more power from the fusion core, allowing for longer time spent in combat. Like the D-42, the D-64 has the strength amplifying hydraulics that are this series trademark. D-64 is the first D-Series armour to posses an internal oxygen supply, allowing for EVA and other oxygenless environments. Like the D-42, the D-64 has recently entered the civilian market.

=== E-01 Power Armour ===
Developed postwar in 2554, the Experimental-01 Powered Armour is a pet project of ONI's. Intended for the use of by Spec-Ops operatives, the E-01 is a closely guarded secret. Unlike previous models, the E-01 has no helmet mounted flashlight, instead possessing night vision as an option on the HUD. E-01 is also the first model in the D-Series to have energy shielding, along with an upgraded fusion core. As of yet, ONI has made no attempt to make the UNSC aware of the E-01's existence, and operatives wearing it have only been assigned to locations such as midnight facility. The E-01 also has an infinite oxygen supply, by recycling the user's exhaled air.

=== D-59 Power Armour ===
The D-59 is not an official model produced by Misriah, and the company is not even aware of the existence of the armour. Instead, it was a field model produced by the UNSC on Sardior as an attempt to turn the tide against the Covenant. Taking the basic model of the armour and upgrading it, the D-59 was mass-produced by the factories that the UNSC had under their control. In terms of specifications, the D-59 is superior to the earlier D-42. Possessing superior strength altering hydraulics, the D-59 is unique in that it also possesses modifications to the speed factor, with the hydraulics being altered to amplify speed as well as strength. This is amplified by the fact that the D-59 is also comprised of both aluminium and pure titanium, offering a more lightweight approach. With a refractive coating similar to the one employed by the first model of Mjolnir, the D-59 is capable of taking low-level plasma hits, although more potent plasma blasts are more than capable of eliminating a soldier equipped with this model. The D-59 is also equipped with a 30 minute oxygen supply, though it has been known to fail in certain situations.
