Imagine you were an invading force floating off the Coast of another country, far enough out that you're practically invisible.. you send your scouts in who are massively technologically superior, adaptive to any environment and use a two stage relay system of drone ship 'spears' to relay info back to your fleet.
You'd expect to get some data back right? Like "this is the enemy, this is what they look like, this is what the lay of the land is" even that is BASIC stuff. Instead your scouts come back, one at a time, in a series of waves every few hours, lobotomized.
Not, damaged, wounded,
