Re: AVENGERS: Grade, Reviews, Discuss, DVD & Sequel **SPOILERS**
The Chitarui ground forces all had electonic implants around their head and neck, the various Avengers pulled them out killing the trooper instantly in each case, when the mothership is nuked the implants on the rest spark and fry, either a serious interupt problem or a suicide protocol built in.
It seems much like the Borg, they troops used for combat are disposable, in the event of capture or failure they selfdestruct in some form.
Or, in my interpretation, a failsafe if Lok decides to betray Thanos by closing the portal to keep Earth & the Cube to himself.
Portal is closed, no signal for mothership, Chitauru are off.
