From a New York Times story by Andrew E. Kramer headlined “Trading Books for a Rifle: The Teacher Who Volunteered in Ukraine”:

Just over a year ago, Yulia Bondarenko’s days were full of lesson plans, grading and her students’ seventh-grade hormones.

When Russian missiles shattered that routine and Russian troops threatened her home in Kyiv, Ukraine’s capital, Ms. Bondarenko, 30, volunteered to fight back, despite her lack of experience, the grave risk to her life and Ukraine’s apparently impossible odds.
