As Ares stated, prep never involves recruiting help. They would have otherwise simply been given allies in the title or OP. Also, virtually nothing y'all are calling for can reasonably happen within an hour.
As said, none of your suggestions reasonably fit an hour timeframe, and this is no one else's fight either way. I know you're not so ignorant that you would believe such either.
Lol sacred108 did this same shit with me before but however prep does not mean assistance I do think chief would take out cap or deathstroke but not sure at same time. He is faster, stronger, and more durable than them just not sure he fare well with caps shield and deathsrokes sword.
"Having prep" and "getting others to do your fighting for you" aren't the same thing. Furthermore, this is "Master Chief and Solid Snake vs. Deathstroke and Captain America", not "Master Chief and Solid Snake vs. Deathstroke and The Avengers".
This is no one else's fight, and trying to say otherwise would be an attempt to give them something they aren't allowed. It's otherwise pointless to feature them in a thread.

Captain America can dodge bullets. "...possible for him to dodge gunfire even in point blank range from multiple gunners at the same time..." and "...able to dodge bullets because he sees faster than them."
Captain America does not get tired. "...can exert himself at peak capacity for a hour without any rest and before showing any signs of fatigue."
Captain America is a frakking tactical genius. "... possesses an eidetic memory, meaning that he never forgets anything and has perfect recall. This enables him to remember any military tactic and apply it to any situation."
You gave him an hour to prep in an abandoned naval yard. He might not be able to outpunch MC, but he has consistently shown that he is able to take out characters much stronger and durable than he is.
Since MC can't shoot him, and Cap has had an hour to think of a plan to deal with MC and Snake, I know who I'm betting my money on.
