Law enforcement forces in Ukraine were conducting simultaneous raids at dozens of military enlistment offices as part of a sweeping corruption probe coinciding with its key counter-offensive, according to the Ukrainian government.
"Law enforcement officers have uncovered large-scale corruption schemes in almost all regions of the country," the office of the prosecutor general said in a statement.
It said police under its supervision were carrying out searches at more than 200 recruitment facilities across Ukraine.
"In return for an illegal benefit, the officials helped citizens to obtain disability certificates or to be recognised as temporarily unfit for service," the statement said.
Kyiv has been conscripting Ukrainians for assault battalions for its counter-offensive against Russian forces in the south and east of the country.
The move reflects Kyiv's efforts to clamp down on corruption as part of reforms requested by Western institutions like the European Union, which Ukraine hopes to join.
Earlier this month, Ukrainian President Volodymyr Zelensky dismissed officials responsible for military conscription in each region of the country accusing them of graft that he said could amount to treason.

At the time, Mr Zelensky said a state investigation into centres across Ukraine had exposed abuses by officials ranging from illegal enrichment to transporting draft-eligible men across the border despite a wartime ban on them leaving the country.
He said 112 criminal cases had been opened in a wide-ranging probe launched after a graft scandal at a recruitment office in Odesa region last month.
Mr Zelensky said that any sacked army recruitment officers who are not being investigated should head to the front to fight for Ukraine "if they want to keep their epaulettes and prove their dignity".
Tens of thousands of Ukrainians have been killed or wounded in fighting since Russia invaded in February 2022.
Ukraine has increasingly faced recruitment challenges as the war, now in an brutally attritional phase, approaches the 18-month mark.
The military has been occasionally hit by scandals involving corruption or heavy-handed recruitment tactics.
Last month, the head of the Odesa region's recruitment centre was ordered into pre-trial detention on suspicion of illegal enrichment. Ukrainian media reports found his family had acquired lavish property in Spain.
Videos purporting to depict army recruiters aggressively pursuing or becoming violent with would-be draftees have gone viral on social media in the country, which has been under martial law since the invasion.
