The US Army has tested a new mysterious weapon "670" at the Fort Irwin base

 

A mysterious weapon was fired from a Bradley combat vehicle during an exercise.

Recently, the M2 Bradley tank launched a new projectile from its TOW anti-tank missile launcher during major US Army test events.

This is the installation of the BGM-71 TOW to launch something else, called simply "670", which does not seem to have been demonstrated before.
