Pic not related so maybe people will actually read the OP.
Team 1: A fire team (4-5 men) of Instagram "operators" à la Lucas B*tkins with all the gucci gear that's legal for civilians to own of their choosing. (No fully auto/burst, RPGs, etc).
Team 2: A platoon (40-60 men) that consists of 50% rednecks and 50% disaffected yuppies with minimal to no firearms experience. They're ONLY ARMED with mosin nagents including bayonets. The leadership are all combat vets, but the regular rifleman are either just rednecks or yuppies with no significant military or combat experience.
Running out of ammo is not a concern for either side. Also the engagement begins when both groups spot each other 100 yards apart after each cresting a hill separated by a saddle.
Also feel free to do the same scenario, but change Team 1 to actual US special forces with access to military weapons (autos, rockets, etc) however only what they can bring themselves, no mortars, airstrikes, etc.
