Alexandr Senaviev, Russia (SPETSNAZ)
Operations and Logistics /Infrastructure
INDEX Operational Valuation
Senaviev was vocal about joining REACT despite Russia's reluctance to continue in the Rainbow program following the re-emergence of Chimera. (Cross-ref: Operation request /Senaviev, Alexsandr)
Excerpt from recent profile update - ".. the emergence of Chimera hasn't changed Alexandr's worldview in the least. He takes things as they come. If anything, he sees it as an opportunity. And also a duty, because he has the ability to do something about it."
Senaviev wants to be integral to a team, to feel useful. (Cross-ref: psychological profile)
EXTRAPOLATIONS:
Assessing influence on team dynamics: Despite Senaviev's boisterous attitude in the face of danger, he is recognized as a calming influence during operations. Possibly an effect of his confidence. He will be an asset to have in high-stress incursions against the Chimera. (INSERT: J. Trace - Couldn't agree more. The Lord's a beast.) (Context Query: "beast" ... UNDEFINED)
Speculating on Senaviev's motivations: He is driven to do what's right using the means at his disposal. (QUERY: altruistic)
Senaviev's resistance to upgrade some of his archaic weaponry defies explanation. (INSERT: A. Senaviev- Bah! This machine knows nothing.)
