This would be a pretty fantastic system for Ukraine, as well as other smaller militaries relying on 'technical' type pick up trucks.

APKWS is apparently in the last big tranche of gear from the US to Ukraine.  It's not crystal clear what the launch platform is, but I suspect integration with aircraft is likely to be too time-consuming.  So a ground launcher is quite plausible.  And probably implies that there is a current US user (USSOCOM most likely).
