MJ12 Obsidian power armor

The MJ12 Obsidian power armor is a suit of power armor used by MJ12 Commandos in 2052.

Background
The final version was created and fielded in 2052 for Majestic 12, using improvements to the original power armor design by a development team under Mark Bates. With improvements from MJ12's Hong Kong and Zurich laboratories, the suit is an incredibly capable light weapons platform excelling in NBC battlefields and riot control, powered by standard bioelectric cells. In the words of the project lead, you can pull it off the shelf and it will work perfectly.

Commando detachments were in the process of refitting and assignment to MJ12 facilities worldwide, starting with the bunker beneath UNATCO Headquarters and MJ12 facilities under the Hong Kong VersaLife facility.

Characteristics
Spotted Denton:  "He's not moving; let's do a scan. " "This one's got strange augmentations." "Scout 50 meters, lockdown." "Do a sweep; this sector's still live." Critical damage: "Secondaries online." "Lost the primaries...compensating." "Video's gone. Enhancing." "Transducers down... switching to visuals. " Going for alarm: "Reinforcements -- move on my sector." "Perimeter breach -- standard attack. " "Alert -- our sector is live, repeat, live. " Found body: "Got a body here. " "Body here - IR's showing a recent death." "Human casualty. Some fluids here -- looks violent. " Idle: "Commandos are just overkill on a job like this. " "Lots of noise in the shortwave. Could be nothing." "Nothing on ultrasonics. I'll try a low-frequency reading. " "Cosmic rays coming through...beautiful. " "Quiet here. Could use some action." "(hums)" "(burst of static) " "(sighs)" "I am prepared to perform my duties." Lost target: "Attempting to re-acquire." "Still got movement." "Can't see him. Checking sonics. " "Running search pattern." Alerted to sound: "Got something -- I'm doing a scan. " "Sonics are spiking -- I'll do a check." "Something's in here." "Hear that? I think we've got a bogey. " "Readings all over the scale. What's the deal?" Denton spotted:  "Visual! Unidentified suspect. " "I've got line of sight. " "Halt! Please give your ID." "Bandit! He's close! " Alert to idle: "Looks like a false reading." "Nothing. I really have to get my sonics checked. " "Must have been a glitch." "Null readings. Continuing scan." Denton spotted again: "Target's here! Very close!" "Locked on - funny reading on this one. " "It's him. Terminating now." "Target locked." "Contact! I've got contact." Target lost: "Where'd he go? I'm running a playback." "Lost him. Don't know what happened." Thermoptic camo does work against the armor's sensors.
 * Sophisticated scanning suite, providing detailed environmental scans across the visual spectrum, as well as the ability to listen across the soundwave spectrum, from low frequencsies, through shortwave, to ultrasonics. Notably, sensitive enough to pick up cosmic rays. User operates in an augmented reality, generated using the suite's input; damage to transducers, video, or any primaries can be compensated for with secondaries or by switching to direct visual observation. MJ12 Commando barks: Comment: "MJ12 Commando barks should have a slightly tinny, over-the-radio sound"
 * Integrated rebreather, making them invulnerable to aerosol, gas, and toxicological attacks.
 * Heat-dispersing microcore foam, negating heat damage from flame and plasma attacks.
 * Ballistic shielding, providing significant protection from small arms fire.
 * Two 7.62mm machine guns and short range rocket launchers.
