A day after President Vladimir Putin announced a call-up that could sweep 300,000 civilians into military service, thousands of Russians across the country received draft papers on Thursday and some were being marched to buses and planes for training — and perhaps soon a trip to the front lines in Ukraine.

Putin’s escalation of the war effort was reverberating across the country, according to interviews, Russian news reports and social media posts. As the day wore on, it became increasingly clear that Putin’s decision had torn open the cocoon shielding much of Russian society from their leader’s invasion of a neighbor.

Mothers, wives and children were saying tearful goodbyes in remote regions as officials — in some cases, ordinary schoolteachers — delivered draft notices to houses and apartment blocks. In mountainous eastern Siberia, the Russian news media reported, school buses were being commandeered to move troops to training grounds.
