Do they now ask you in Basic Training if this is not what you maybe want and to raise your hand? And then you can get out?

I'm hearing this story from a friend's ex-husband who claims they were given the option to raise their hands if they felt "this wasn't for them" and then they could just get out. Which seems very odd to me considering how many opportunities you have to decide that before you get to basic. To just nope out once you arrive. I admit it's been a minute since I went to basic but I don't remember this being a thing.
