Another aspect people are missing is that this mass ATGM/MANPAD spam is...abnormal.
Thousands of MANPADs and ATGMs have flooded into Ukraine; while the Ukrainians have asked (per CNN) for 500~ Javelin and 500~ Stingers...PER DAY.
To put that all into context, in 2014 Finland spent EUR 90 million (about $123 million) for the FIM-92 RMP Block I Stinger to replace their existing pile of Soviet era MANPADs.
The original contract "Wish List" was $330 million for 600 RMP Block I Stingers, 110 Firing Units, and 110 night vision sights.
So we can guesstimate that Finland actually bought only about
:
200 x Stinger RMP Blk I
40 x Firing Units + IR Sights
That's not a lot for a modern battlefield; especially if you might use 3 or more Stingers in an ambush pocket -- one guy fires a Stinger at a Ka-52 Alligator; the pilot sees it and flares go out and it evades....
...only to find out that the Ukrainians have carefully positioned several more stingers to the sides of the main shooter; so that no matter which way the helicopter evades, it's turning towards a Stinger Shooter.
