Nope, apparently not looking for Bergdahl the Army says

Sara Koenig, Was Anyone Killed Looking for Bowe Bergdahl? Some Hard Evidence at Long Last, 6 October 2016.

After nearly a year of waiting, [Serial has] finally received the Army’s internal investigations into the 2009 deaths of six soldiers from Bowe Bergdahl’s unit: MW, CB, KC, MM, DA and MM.

None of these investigations report that any of these men was on a mission to look for Bergdahl. Neither Bergdahl’s name, nor the term DUSTWUN (shorthand for a missing soldier), appears in any of the documents.

What follows are in the post are excerpts from the Army 15-6 (informal investigation) into the deaths.  The post concludes with this interesting piece, which means the “discussion” will continue.

This report includes an extensive discussion about what went wrong on this mission. It says the patrol was horribly planned and badly executed in every possible way. Which is in line with what some soldiers and commanders told us in interviews: that in the days and weeks right after Bergdahl left his outpost, there was such a scramble to find him that soldiers were sometimes left under-equipped and vulnerable. But whether any deaths can be attributed to the search for Bergdahl, according to the Army, the answer seems to be no.
