@TheInsiderHimars are equivalent of our TRG-230/300 systems, basically mobile rocket artillery launcher. As @TheInsider said, this is our GLSDB (Ground Launched Small Diameter Bomb) equivalent. Which, I might be wrong but, only the second system like this as far as I know.
Again, i don't write this to look like a smart as* and please don't get me wrong. But if you guys write it is "equivalent", then don't you think that someone, who is not familiar with the subject, will look up GLSDB and think like "Göktan will have same range, dimensions and capabilities"? Wouldn't it be more correct to write "same concept"?
Afaik according to the small amount of information we have about Göktan, it should be far better than GLSDB.
