Petitions calling for Volodymyr Zelenskyy to offer Hero of Ukraine awards to fallen soldiers have been popping up almost daily in recent weeks.
Since 2015, petitions have been used as a platform for popular appeals to the Ukrainian president.
But they have taken on a new role during the war, with the families of soldiers killed in action using them to call for them to be honoured with the highest military award.
Some 2,000 petitions have been submitted since the war began.
Although the Ukrainian government does not disclose its losses, Western intelligence services have estimated tens of thousands of Ukrainian soldiers have been killed.
Fewer than 400 service members have been named Hero of Ukraine since the war began, many of them posthumously.
Anna Birzul’s younger brother was killed in fighting in eastern Ukraine in November.
While stricken with grief, she quickly sprang into action to launch a petition.
“We buried him on the 26th, and already on the 27th I had written it,” said a tearful Ms Birzul, 35, standing at her brother Bohdan Krotov’s grave in a Kyiv cemetery.
She said he had hauled wounded men off the battlefield and rescued them under heavy fire, before being killed himself.
He saved four people, she said.
