In the electro-optic countermeasures (EOCM) arena, the Army has been working for a number of years to degrade an adversary's targeting and night-fighting capability.
Developed in the late '80s by (then) Martin Marietta Electronics and Missiles Group (Orlando, FL), the Stingray is a 350-lb EOCM system designed to fit aboard a number of ground vehicles and helicopters.
The LCMS is a rifle-mounted EOCM system with a self-contained target acquisition system.
While EOCM systems appear to be the best answer to the proliferation of battlefield EO systems, they have attracted substantial criticism from groups such as the Helsinki-based Human Rights Watch because of their potential to temporarily or permanently blind humans.
To date, no US EOCM systems have entered production.
