ISF Shadows of the Void?

In Mendrugos fiction reviews, he mentions that he suspects that an operation was conducted by a unit called "shadows of the void"

Do we have any evidence that this unit exists?

We know that the BattleMech company that dropped on Crossing at the climax of the battle with the Dragoons was a DEST outfit called the "Knights of the Void" (reference NAIS Atlas of the 4th SW).  That at least establishes that the name "Shadows of the Void" is plausible by convention.

I'm pretty sure they're called the Sword of the Void, aren't they?
