This is just an update to the old Chappral (Sidewinder) anti-aircraft system of the 70’s, 80’s, and 90’s.

Sounds like the military is returning to tank warfare. This configuration is used to defend tanks from aircraft attacks.
I led two Chaparral platoons back in the 70s. I've been out of the Army so long, the battalion I served in was deactivated at least 15 years ago.
Thanks for the ping and the link. It makes sense to update this old system.
