David Axe points out that Ukraine is using #glsdb on modified Ukrainian MiGs, giving them a somewhat less powerful but more accurate glide bomb, usable on - let's face it - their most common, most expendable jets.

Axe says "no one outside the Pentagon and Ukrainian air force knew the Ukrainians had the... SDBs".

Not quite. I mentioned them on Jan. 31st, as #glsdb. And that they could easily be converted back to SDBs, usable on F-16s... or, apparently, on the MiGs modded to launch US HAARMs.
