There are different kinds of essential. The fact is that you have no idea why she was coming, no information whatsoever, but still you made an assumption. No, no military will stop to function and no people will die, but those are not only essential reasons. Military safety and health are not the only fundamentals for human life. Me missing her is just my feelings, it is not the reason why she needed to come. I’ve made every necessary precaution since COVID started, even more. I’ve been for restrictions and pushed the my close-ones to heed all the advice and to make even more precautions. Me asking about it (or not understanding some details for that matter, as why the first test was necessary, which btw was perfectly and calmly explained earlier, and I’m thankful for that) does not indicate in any way that I’m against the whole thing. If someone smarter than me says I and everyone else will be safer doing this or that, I’ll listen to them. It only means that I’m looking for information that I do not fully understand and there’s nothing wrong with it at all, as well as there’s nothing wrong with feeling frustrated about it. I just hope there aren’t many people who asks for help or information and gets so aggressive answers, full with assumptions, like yours. What you SHOULD do is explain what’s asked and show some compassion and understanding.
