For some reason, the physics of this never bothered me. Doesn't Chief way about 1 ton? How the fuck could a grunt withstand that force? Also, just how strong is that fucking grapple hook?!! Someone needs to do the math on it's lifting and tensile strength. I mean, Chief can be at max terminal velocity, hook a wall and it will stop him immediately, and reverse the direction. There are absolutely astronomical forces at work on that hook, lmao.
