the sweden developed the n-law missile as a  shoulder-fired man-portable armor-defeating  

infantry-level weapon the rise of the mbt in the  cold war decades gave rise to increasing potency  

of tank killing systems in turn culminating  in the many useful options experienced on the  

modern battlefields of today design of the  n-law missile began by sab bofors dynamics  

in 2002 utilizing key qualities of several  well-tested developmental systems as well as  

those accepted into the at4cs model of 1987 this  adopted by the united states army as the m136  

the end result is an appropriate answer to  the constantly evolving threat that is the mbt

the n law fires a 150 millimeters missile at  subsonic speeds out to an effective range of  

600 meters with a maximum range of 1000 meters  listed the system includes the launcher which is  

disposable after a single use the launcher  includes an optics set as well as its own  

power supply and features a basic tube  form with accessible muzzle and breech  

the open breach nature absorbs much of the  recoil force which allows the n law to be  

shoulder fired by a single person usually  over the right shoulder overall weight is  

12.5 kilograms with an overall length of 1016  millimeters allowing for inherent portability  

at the infantry level a shoulder strap is  provided in this way several n-laws can be  

carried into action by riflemen and brought to  bear when needed providing effective portable  

tank-killing firepower against unsuspecting tanker  crews from nearly any angle as an armor-defeating  

weapon the n-law can also be utilized against  fortified structures with good results and holds  

the inherently quality of being able to fire from  enclosed spaces extremely useful in urban fighting

the missile initially clears the launcher before  igniting its propellant to provide an added safety  

measure for the fire initial velocity is rated  at 131 feet per second and minimum engagement  

range as 20 meters for additional safety  guidance is achieved through a predicted  

line of sight system and inertial guidance while  the warhead seated on each missile can attack  

targets through a top-down angle usually the most  vulnerable of any armored vehicle including mbts

in swedish army service the n-law has been  adopted under the rb-57 designation the  

weapon has also been taken under use by the  armies of finland indonesia luxembourg and  

united kingdom as of november 2013. the finns  designate the type as the 102 rslpstohjn law  

while the british army have replaced their aged  stock of law 80 and ilaw weapons with the mbt law
