The MGM-166 LOSAT (short for Line-Of-Sight Anti-Tank) was an anti-tank missile system developed by Lockheed Martin in the late 1980s–mid-1990s, which peculiarly relied on a purely kinetic missile to engage enemy armour. Able to reach speeds of up to Mach 4+, the projectile could reach its maximum effective range of 4km in under 4 seconds, making evasion almost impossible, and due to the projectile’s sheer size and weight (2.85m and 80kg respectively), it would easily eviscerate anything it impacted. Plans primarily revolved around a “scoot’n shoot” style doctrine with a quad pack of LOSAT missiles on top of a HMMWV carrier vehicle, but there were also plans to mount the system to both the M2 Bradley and XM8 AGS. The LOSAT was ultimately abandoned in 2004 due to various flaws—namely long reload times due to the large missile sizes, poor versatility against light targets, exorbitant costs, and poor performance at closer ranges.

The LOSAT was introduced during Update “Sons of Attila” as a reward for the 2023 Tokushu Heiki event. As the name implies, the vehicle requires a direct line of sight to its target for its missiles to hit, which makes the LOSAT vulnerable to return fire. Due to the damage effects of the missile being entirely kinetic, at closer ranges the LOSAT is quite ineffective; however, at long range, when allowed to accelerate up to full speed, the missile can penetrate virtually anything without much hassle. The LOSAT is best played on a large, preferably flat map with few terrain protrusions, as the vehicle lacks gun elevation/depression and requires a direct line of sight to its target. Its high mobility allows it to take advantageous positions quickly, and is its greatest strength, while its armour is thin and should not be relied upon. While lacking in versatility, when positioned effectively to hold a critical long-range sightline, a LOSAT will truly be a force to be reckoned with.
