Try running your Stinger test against the Russian Zala drone.
I tried looking up the cost of a Ural-4320 truck. I can't find what the Russian government pays for them, but in mint condition they go for $26,000. Per unit cost for a US FMTV A1R is $160,427. I think people may complain if US trucks cost 6 times Russian trucks
