Hi there!
This is one of my sci-fi project
StingerHead-36 // SH-36
It is a defensive turret with medium range of missile, ground to air type. It has a radar scanner at the backside of the turret, detect the enemy in range of 20 KM. Heat tracker on the moving object is the absolute ability in it's defensive system.
Thank you!
Have a good day
