I can confirm these are available as a mission reward (got one from M Prime farming Stalker), along with Health Kits from the mission types that give out a random reward (think it's capture, spy, and another one). So far I've done M Prime dozens of times, only ever gotten one of these and two Health Kits. It's just exceedingly rare.
