Echo One Sierra-7A, abbreviated as EOS-7A (UIN:EOSC17S07A0922), other aliases: EOS-7A, S-7A, 7A, "Malchik", is a new addition to the Sierra-7 fireteam. As a rookie member, he is undergoing on-the-job training under the supervision of Ordinal Sierra-7 (OS-7). In the absence of the Ordinal, oversight duties fall to Echo One Sierra-7D.

S-7A's figure is slim, his skin is darker than 7D's, his eyes are brownish-green, unit's height is approximately 173 cm.

Sierra-7A's augumentations are very minor, unit is expected to receive enhancements in the nearest future. Currently in possession of:

• Basic sincipital reinforcement plate - web-like metallic structure implanted into his skull, visible from his forehead, in process of full integration with skin tissue.
• Synthetic structures: dental (partial)
• Internal vital sign monitoring system
• IV/IM injection port

S-7A has been reassigned to City-17’s Civil Protection team after serving as a mechanic at the Vehicle Repair and Manufacturing Facility in the University District of C-17. The unit has been offered a promotion opportunity to join the Combine Armed Forces, following one year of service as a CP officer and a satisfactory performance evaluation.

Sierra-7A is of a lighter build, making him effective for quick movement in the field—though this proves problematic when handling heavier weapons. His combat style reflects these traits, as he reportedly favors the use of the 9mm pistol over the Pulse SMG. S-7A’s height and overall agility make him particularly suited for navigating enclosed spaces and areas that pose challenges for other units. Sierra-7A has been reported to struggle with maintaining composure in high-stress situations. Dissonance suppression has shown limited effectiveness, the presence of his teammate, EOS-7D, appears to have a significantly more stabilizing effect on his mental state. The unit is currently undergoing mandatory conformity training focused on enhancing strength and discipline.
