Regarding the suitability of the RBS-15 for different targets===
As noted when someone did undo my edit that removed the statement about the RBS-15 being "just too large (and too expensive) for most targets", this statement in the text was supposed to be referring to land targets. However the meaning of the text, as it stands now and as it stood before my edit, gives the impression that the RBS-15 is unsuitable for the majority of all targets, naval targets included. So, unless someone provides a cedible source that the RBS-15 is too large and expensive for all types of targets, the text has to be changed from it's current form, since it is highly misleading. 

I'm gonna revert the last undo undo and add information to the text that the RBS-15 is "just too large (and too expensive) for most types of land targets". This is I accept as highly plausible and I am happy to see it included in the text. (On the other hand, someone could make the case that it probably should be included that the Polypherm is too small for many targets, but I don't care that much, so let's leave that out.) I hope this is satisfactory to everyone.
