And soldiers are heavily trained to try and avoid getting killed, especially by friendly fire. People seem to think there's some contradiction here, but there isn't. Nobody wants to unnecessarily run the risk of being injured, perhaps permanently, by their own side.

And it is unnecessary. COVID was already almost always mild for people outside of risk groups like the elderly (who aren't serving in the military anyway), and Omicron just took that mildness to another level. It just isn't necessary for this CO to get vaccinated against Omicron, especially as the vaccine effectiveness has gone negative i.e. not only can they get it anyway after vaccination but they're actually more likely to.

Moving the goalposts. Issue under discussion is "side effect risk for men under 40 is non trivial".
