The Intel folks are most likely getting some good dope on the latest Russian weaponry that was left behind damaged and abandoned.
Much like the Russians and Chinese got looking at ours abandoned in Afghanistan.
I don't know how cooperative the Ukraine is with US intel right now on the giving side and Russian tanks and BMPs are pretty well understood.
On the other hand the A2AD systems in Belarous and Russia are sure as schitt getting much attention for all our ECM platforms.
F-35s are going to be sucking up all the signals and the SAR radars are IDing ground targets for the data bases.
