Autoloader is both advantage and disadvantage at the same time. You don’t need another crew member, but the mechanism proved itself to be deadly when tanks get hit.
The weight itself is a huge factor though. Modern tanks get to absurd numbers where it’s getting difficult to operate them at all.
Hello fellow universal donor. I’m blessed with the same blood type, so I donate the blood when I can at my local hospital. Usually 3x a year.
At first there was not much thought behind it, as both my parents went there too. When I turned 18 they just asked: “Do you want to go too?” And my answer was obviously yes, because why not? It was day off school, after all.
Now it’s just automatic. Since I only donate in my local hospital (small town, 15k people) I believe my blood gets to help people. They don’t pay for it, it’s volunteer, organized by red cross. They used to cover bus ride, but lately switched that for “food stamp” instead. We also get juice, coffee and snack once donated. The good part is, it’s still day off work where I live.
