I wrote the “What is the infantry” series back in those heady days of the summer of 2013, when the topic of women in the infantry was hot. Since having rejoined the Army in 2011, it has been the topic du jour, easy banter while sitting on rucksacks after a field problem waiting for trucks, or a thing to get enraged about over on Twitter late on a Friday night. The chatter has calmed down now with women having successfully completed the United States Marine Corps infantry course (enlisted), although there are still spurts here and there, like when 2nd Lt. Sage Santangelo penned an op-ed in the Washington Post arguing she (and others) should be allowed to retake the course. Just yesterday, Iraq and Afghanistan veteran Tessa Poppe addressed the topic here on Task & Purpose.
