Ukraine needs tanks and heavy artillery, not training.
A recent report from the Atlantic Council, the Brookings Institution, the Center for a New American Security, and the Chicago Council on Global Affairs listed what they think Ukraine needs.

“Additional non-lethal assistance should include: counterbattery
radars, unmanned aerial vehicles (UAVs),
electronic counter-measures for use against opposing
UAVs, secure communications capabilities, armored
Humvees and medical support equipment.
Lethal defensive military assistance should include light
anti-armor missiles, given the large numbers of armored
vehicles that the Russians have deployed in Donetsk and
Luhansk and the abysmal condition of the Ukrainian
military’s light anti-armor weapons.”
