Trophy (Israel Defense Forces designation מעיל רוח, 'Windbreaker') is a protection system for military armored vehicles. It is termed an active protection system (APS) and is designed by Rafael Advanced Defense Systems.

It is designed to supplement the standard armor of light and heavy armored fighting vehicles. The system is in active use on Merkava Mark 4 tanks and the Namer armored personnel carrier (APC). It is also found on the Abrams M1A1/2 tanks, and has been tested on Stryker APCs and Bradley Fighting Vehicles.

The Trophy system protects against a wide variety of anti-tank threats, while also enhancing the vehicle's ability to identify enemy locations.

Trophy's first production manufacturing contract between IDF and Rafael was signed in 2007. Israeli Government/IDF Safety certification was granted in 2010. First deliveries began immediately afterward. The design is centered on the Elta EL/M-2133 F/G band fire-control radar with four flat-panel antennas mounted on the vehicle, this provides a 360-degree sensing field around the protected vehicle.

The system allegedly relies heavily on high-speed computational technologies. Upon detection of an incoming projectile, the system automatically computes various parameters, such as the approach vector, nature of the threat, time to impact, and angle of approach. The defensive projectiles are launched by two rotating projectile launchers positioned on the sides of the vehicle. These launchers deploy a number of small EFPs (Explosively Formed Penetrators), forming a precise and closely spaced matrix, targeting an area in front of the anti-tank projectile. The system has been engineered with a narrow kill zone to ensure the safety of friendly personnel in proximity to the protected vehicle.

Trophy is a system that enables connectivity to other technologies, such as soft-kill, C4I systems, remote-controlled weapons stations, etc. The system is designed to defend against many types of anti-tank guided missiles, rockets, and high-explosive anti-tank (HEAT) rounds, shoulder launched weapons such as rocket propelled grenades and recoilless rifles.

The system can simultaneously engage numerous threats arriving from different directions, it is effective on stationary or moving platforms, and is effective against both short- and long-range threats. Newer versions of the system include an automated reloading feature for multiple firings of defensive counter projectiles. Rafael's development program for the system includes an enhanced countermeasures unit - to be available in the future, to protect against kinetic energy penetrators.

Based on data from 2013, adding the Trophy system to a Merkava Mk. IVM potentially adds 30 percent to the cost of each vehicle.
