Anyone familiar with HtH combat can tell you that if you think you should be putting wrestling moves on someone in combat, you shouldn't even think of real fighting. It is fine to practice one-on-one, but just maybe the super-mutant will toe out a line separate from the others, and stand with his back to a stepladder so you can put a headlock onto him.
Actually, the reality of battlefield hand-to-hand combat is: being thrown to the ground in the middle of a multiple-on-multiple melee is about the worst thing that can happen to you (especially if you are wearing 60lbs of equipment at the time). In any fighting system used on battlefields, empty hand striking that DOES occur consists of "surgical" attacks intended to facilitate this, because dispatching someone with your bear hands is ridiculously difficult. It is being tied up with someone for any extended period of time that is generally a bad idea, UNLESS you outnumber your opponent and are restraining him to help your allies attack (which is the only reason I'd even consider a standing hold).
Any elbow-and-collar based wrestling is derived from fighting in armor where you and the opponent are in stalemate, trying to control each other's balance by grabbing at the chestplate shoulder strap (or in more modern times the shirt collar or neck) and elbow joint. The primary goal of any technique from this clinch is to break the deadlock in a way that gives you time to get a weapon out first. The most effective way to do so is to throw your opponent to the ground in a way that ideally also seperates joints and/or knocks the wind out of them. This gives you time to attack his vitals while vulnerable (this is actually partially reflected in Fallout already, since you get a huge bonus to hit a grounded opponent).
This is a VERY basic description of battlefield HtH, derived mostly from my knowlege as nidan in a system of Japanese martial arts dating to their "Warring States" period. It is however a basically universal concept anywhere that armoured HtH fighting took place.
www.aemma.org has a library of european "fight books" which detail many principles very similar to the Japanese arts. This is probably because, through a process of trial and error, fighters found out that some things were just good ideas.
Obviously it is ideal to attack the enemy from farther away, which is why ranged weapons have always been the cause of the vast majority of battlefield casulties regardless of era. But if you DO end up in HtH range, throwing the other guy to the ground is better than any kick. I never understood why FO1 even had that silly head-level round kick.
And just for some amusement, Flash Gordon doing what's known in the art I practice as "onikudaki"
that could be cool to see , maybe it would fit , not alot but a few
