This is the BMP (Benjamin Military Productions) Halftrack AA-Gun.
The BMP Halftrack series are all 3 man operated and can be used in the most differend and hardest situations. It has a 5 liter V8 twin-turbo with 753 BHP. It can climb hills to 41 degrees and hang over 45 degrees sideways without tipping over.
It comes standard with night vision camara and wallbreakers mounted on the front. The cargo area is can fit 4 stretcher or 6 troopers.
This AA-Gun version has 4 50. MM canons with a accurate ranch up to 6500 feet thanks to radar lock.
Although the colour schemes a bit whacky (with the bright green) the design is really good. It's like a modern version of the WWII Flakpanzer. I love mobile AAs but you dont see them very often. This ones worth the wait. Come and see my stuff.
