NAVAir Spike F2M2 is a 2.4kg missile all up. The warhead is 1lb (454g) EFP. Range is 3.2km+
A 5kg all-up missile with the same warhead could probably round that up to 5km.
If you take the write up for the ZR-1500(?) and the experience from the Ukraine conflict, something like this "close defense vehicle with 12 micro missiles" can possibly protect SAM batteries, artillery batteries, command posts, etc from loitering munitions like Lancet and Spike NLOS.
Alternate use in a man portable role is definately anti-vehicle and anti-hardpoint given operational experience of troops proclivity to expend very expensive atgm on similar tasks. (Oh yes, anti drone too - lest the drone brings the heavy metal rain)
