Important research given the current state of the war, and the lessons that are being drawn - perhaps erroneously - about the future of manoeuvre, armoured vehicles and the mix of weapons and capabilities needed to survive and succeed on the modern battlefield.

Detailed analysis of the kind of targets in scope if (a big 'if') the US provides Tomahawk to Ukraine. But my (admittedly superficial) view is that achieving an impact on the 'front line' will be hard, primarily because it's doubtful the US would provide the volume required.
