The RB57 NLAW/ MBT-LAW The RB57 NLAW, also known as the MBT-LAW, is a one-man disposable anti-tank system that weighs 12+ kg (over 25 pounds), with a range of 20-600m (just over 1/3 mile). It was designed to kill tanks, and also to overcome the traditional difficulties faced by soldiers, such as complicated firing routines with estimation of range, wind direction and target speed. Because it’s a short range weapon, it uses a simple “PLOS” (Predicted Line of Sight) approach where the soldier tracks the target for a few seconds before firing. The missile’s guidance electronics record the soldier’s aiming movement, then calculate and predict a flight path to the target. Once launched, no further guidance is required; the missile’s inertial guidance tells it where it will need to be. Against tanks and other armored targets, the weapon’s OTA (Overfly Top Attack) mode is used. Flying about 1m above the line of sight, the missile’s electronics sense the dense metal beneath and detonate above the target’s most vulnerable part – the roof. When facing lighter vehicles or fortified outposts, the DA (Direct Attack) mode can be used instead. for direct attack, the missile flies directly at the target. The sensors designed to detect the target below are disconnected, and the warhead fires shortly after impact. The weapon is fully compatible with night vision goggles for use at night, and can also be fired from “confined positions” like the inside of a building, without barbecuing the firer and squad. The launcher is disposable after firing, though the Trijicon Compact ACOG 2.5×20 sight may be removed and retained. Training is very important for man-portable rockets and missiles, especially as units prepare for international deployments where combat is a real possibility. It’s even important during international deployments, because these missions often last longer than expected, and skills need to be kept up. It can also be very expensive, however, if live missiles are used. These factors have led to a strong expansion of simulation as a key component of modern man-portable anti-armor missiles. There are 2 kinds of training that typically comes with the most modern anti-tank missiles, and they are not entirely exclusive. One option is embedded training, where training software et. al. are included in the sighting and firing system’s electronics. The American Javelin and Israeli Spike missiles have this feature, for instance. Fully disposable systems like the RB57 find that approach a tad expensive, however, opting for integrated indoor virtual simulators that are designed to work with the weapon.
