Prototype medic power armor

MP-47/A prototype medic power armor is a unique United States Army variant of T-45 power armor found in Fallout 3, with an autonomous morphine delivery system.

Background
The MP-47/A model of T-45d power armor was designed to merge field medics and foot soldiers into a single entity, and was planned as an automatic medical supply dispenser, meaning troops would not have to be evacuated for medical treatment. The production model was designed to administer stimpaks and other injectable substances, but as the prototype, this model only delivers Med-X. An on board computer system with verbal feedback response systems has been installed inside the armor, making it so easy to operate, "even a child" could use it. The armor is programmed to automatically detect limb condition; if it is less than optimal, the suit auto-injects Med-X into the soldier. Had the defense contract been extended for this armor, the producer would have enhanced the on board computer to provide command information to field officers, as well include a "self-destruct" system to inject a lethal chemical cocktail into deserters.

Characteristics
This unique suit of power armor is found in the sewers beneath Old Olney and confers identical protection to the regular T-45 power armor. However, it does not boost Strength, compensating for it with a lower Agility penalty (-1 as compared to -2) and higher radiation resistance (+25 instead of +10).

It's primary feature is the ability to automatically inject Med-X when either the player's total health drops below 33% or any limb's health falls below 25%. This effect can occur every 2.5 in-game hours (about 9 minutes real time). Note that while the suit removes Med-X from the player's inventory, it actually applies a different consumable that has zero chance of addiction, provides the regular +25 Damage Resistance, and temporarily suppresses negative effects from crippled limbs (eg. no limping with crippled legs). The effect is identified in the PIP-Boy as Suit Med-X (Ignore Neg Eff +1, Dam. Res. +25.) and stacks with regular Med-X, allowing players to gain a total of +50 Damage Resistance if they use Med-X directly after the suit injects it.

The suit has an integrated voice system (same voice actor as the Mister Gutsy) which will inform the player about the injection. It will also notify them about any enemies present in the area. Beyond that, it's cosmetically identical to the regular T-45, save for a U.S. Armed Forces roundel on the pauldrons instead of the Brotherhood insignia commonly found.

Like every other power armor, it requires power armor training. Unlike them, it cannot be turned in to the Outcasts.

Location

 * Old Olney Sewer: On a dead Brotherhood Initiate inside a locked room on the southern end of the sewers. It's found together with its manual.

Behind the scenes

 * According to the terminals in the experimental chamber at Fort Constantine, the prototype was supposed to be located there.
 * Old World Blues includes the stealth suit Mk II, which uses stimpaks and Med-X automatically, in the spirit of this armor. It also remains in Fallout: New Vegas files as legacy content.

Bugs

 * It's possible for the dead Initiate to despawn if the player enters the sewers and leaves until the cell resets or if a physics glitch causes the body to disappear through the floor. Other assorted glitches, such as items turning invisible, may also deny the armor or make it difficult to collect.
 * The script that plays the sound file upon equipping the armor will always fire, even if the armor is broken.
