Did you read this? This article is about the pro-Russian separatists’ conscription of Ukrainians to fight for Russia.

From your source:

The Guardian recently reported that men in the Donbas region in eastern Ukraine are being forcibly conscripted into the armed forces of the self-declared Donetsk Peoples Republic (DPR) and Luhansk Peoples Republic (LPR).

From the Gaurdian article they’re referencing:

Pro-Russia separatist forces have stepped up the forced conscription of men – including Ukrainian passport holders – in occupied areas of the Donbas region, amid mounting evidence of the scale of losses on the Russian side.

According to credible evidence from the region, forced conscription – already a feature of the Russian-backed separatists’ rule before the Kremlin’s invasion on 24 February – appeared to have picked up again in June, with checkpoints and patrols, some reportedly involving Chechen fighters allied to the Kremlin, on the lookout for men to recruit.

From another article cited by your source:

Russia justifies its invasion of Ukraine arguing it is defending the “Luhansk and Donetsk People’s Republics.” Mere days before Russia launched its attack, when tens of thousands of Russian soldiers had been amassed on Ukraine’s border, these self-proclaimed “People’s Republics” beyond Kyiv’s control launched major mobilization drives. Men between the ages of 18 and 55 are no longer permitted to leave.

Even if Ukraine is using conscripted soldiers, you just proved that A) pro-Russian forces are doing the exact same thing and B) you don’t even look at the articles you’re sharing.
