You've won 1 billion dollars, but you need someone to protect you. Who do you pick?

You've won 1 billion US dollars tax free, your government okay with this so you don't have to worry about legal trouble.

The catch is that a lot of people want a piece of it or all of it, and don't think that you're entitled to the money that's rightfully yours.

Out of these 4, who do you hire to protect you from these people so you can enjoy your wealth?

1: An ex female DEA field agent. She's an expert with pistols and revolvers on par with competition shooters and has a black belt in Judo, Krav Maga, and Jiujitsu.

2: An ex 101st Airborne. He has been deployed to Afghanistan and is very big and strong compared to most people, benching 315, squatting 405, and deadlifting 495.

3: An ex US Marine. He was in the Iraq war and has an average albeit fit build. He was an ex PMC for Triple Canopy as well during the War on Terror.

4: An ex female CIA field agent. She is an expert in espionage and counter espionage, and decently skilled with handguns, shotguns, and rifles. She has the stamina of an triathlon competitor.
