Note: I'm beyond a little miffed at the lack of coverage of LAAD by US "military" oriented news sources.

The Brazilian Army has aquired 36 GEPARD anti-aircraft armored vehicles by Krauss-Maffei Wegmann (KMW).You're seeing a modern day arms race in S. America. That many arms flowing into the region with all the simmering rivalries WILL lead to (if we're lucky) at best a few border skirmishes or at worst a couple of regional wars. Yes I'm a broken record but I have yet to see a Think Tank take on the subject.
These modernised GEPARD include new C3 capabilities, improvement of target engagement with extended combat range, a new fire control unit, shorter reaction time, and better hit to kill probability.
