The last mention I can find of them is in JHS: Terra, regarding their liberation of Zion. Major Stryker announced his intention to join up with Alys Rousett-Marik, but they aren't included in any Scour or Scythe unit listings, nor do they appear in FM 3085, either as a merc unit or, from the names of known members, having turned house regular.
Obviously, I'm a big fan of the unit. :)
