The Starstreak HVM (High Velocity Missile) is a British man-portable air defense system manufactured by Thales Air Defence in Belfast, Northern Ireland. It is composed of a main missile body that can accelerate to Mach 3.5, and three laser-guided sub-munitions.
The multiple projectiles greatly increase the hit probability of the weapon system. The sub-munitions have a tungsten housing that permits deep penetration into light armor and significant damage from fragmentation.
The HVM-II is a weapon featured in Battlefield 4 as a Battle Pickup. It is a laser guided anti-vehicle weapon that can be used against both ground and air targets. However, the HVM-II is far more effectively utilized against Air Targets as the missiles themselves do relatively standard damage against Armored Vehicles such as Main Battle Tanks and Infantry Fighting Vehicles.
As a laser-guided weapon, an active laser lock (whether by the launcher's own system or designation by teammates) needs to be maintained for the missiles to hit their target. While they are still live, the missiles can be trained on a different target, or re-trained on a target that used countermeasures. If the target is destroyed any inflight missiles can be redirected to a new target.
The March 2014 R30 Server patch nerfed the FIM-92 Stinger and the SA-18 IGLA damage to 35% from 45%. The HVM-II is unaffected by this change and inflicts the most damage out of all the Anti-Air Launchers, often destroying most air targets in a single barrage.
