Nuke or seal what should i be?

so i am currently in dep and i am a nuke according to paperwork lol. i like the fact that nuke is mentally demanding but i kinda want to be the most physically demanding too. i have trained with navy seals before and they are tough sh*t but i like the fact they are so hard. i'm not sure if i want to stay a nuke or if i want to be a seal or do both lol like one after the other.
