Biography
In the latter stages of the Federation-Klingon War of 2405-2410, Fleet Admiral Yanishev handed out missions of the fleet action type, i.e. requiring at least twenty Starfleet vessels to respond. 

In 2409, Yanishev coordinated support for the besieged Starbase 24. 

The Gorn advance into a minefield required Yanishev's attention. 

When General D'ald set up mining operations in the Laurentian system, Yanishev pooled Starfleet resources do eliminate this threat. Yanishev sent directions to the forces on surface battlegrounds, space engagements, and the effort to eliminate boarding parties from the USS Daxter. 

Yanishev also directed a Starfleet ship to support the USS Phlox on an archaeological mission in the Hyralan sector. 

The occupation of Deep Space 9 by the True Way troops ed by Gul Emek led to a fierce Starfleet resistance, ending with the elimination of all involved Cardassian ships and boarders. 

Throughout the end of the war and beyond it, Admiral Yanishev organised the defense against aggressive, lone-wolf Branchers, known as Crystalline Entities. 

In 2411, this department was reorganised into Task Force Operations.
