IWS

CWS seems to be on its way out, IWS was 60's or early 70's kit and were considered to big even back then, ive certainly never seen one in the past 11 years ive been serving.

IWS is no more.

I belive Maxi Kite is the same as the CWS just x6 rather than x4. Still made by Thales using the same tecnology. Maxi Kite mainly used with GPMG as the greater range makes best use of the increased maginfication.
