No, you would not have "made a good marine"
You would not have made a good marine. The fact that you say that you would have is enough evidence to go by. You talk loud at the bar so everyone can hear your opinions about how the youth of today suck because they don't perform their civic duty to go kill Russians because they are brainwashed by their professors and communist cable news channels that nobody under the age of 50 watches. You have had 2 Miller Lites and you're already getting aggressive with people. You are a 62yo man who works as an administrative assistant at the local plastic factory. You want to bring back the draft, but also think kids these days are too weak and corrupted by gender skullduggery or whatever to be functioning adults. You want to send a generation of people who are too chickenshit to make a phone call to a foreign country to kill or be killed. Your overconfidence in what a great marine you would have been would be expected in some dumb kid with an invincibility complex, but is just disheartening in a man your age.
