The lack of a clear mobilization strategy — or even agreement on how many more troops Ukraine needs — factored into Zelensky’s dismissal of his top general in February, but the new commander in chief, Oleksandr Syrsky, so far has brought no new clarity.

Syrsky has been tasked with auditing the existing armed forces to find more combat-eligible troops, after Zelensky’s office recently announced that of the 1 million people who have been mobilized, only about 300,000 have fought at the front lines. But nearly a month after his promotion, no one in the military leadership or the presidential administration has explained where those 700,000 are — or what they have been doing.
