Aviation Content here: MANPADS proliferation continues to be a concern (and it has been for a while, going as far back in my memory as Stingers in Afghanistan in the 80's)

Worth a read.
For Nutty: nice piece in terms of perspective.
The entireactive U.S. Army has 330 artillery pieces (M777 and M109 self-propelled guns). Ukraine is asking for 1,500.
As to the later tidbits regarding the area around Karkhiv, and the Russian artillery shooting from inside Russian territory: ALCM is a possible answer to that.
Ukraine has hit a wall in Kharkiv—the closer it gets to the Russian border, the more exposed its forces are to artillery from inside Russian territory, where they sit safe and well-supplied.
The question is, does Ukraine have Russian vintage ALCM's on any of their aircraft? Since Russia has violated Ukraine's border left, right, and center, Ukraine hitting a military target (artillery position) within Russia that is firing into Ukraine is well within bounds.
