In order not to end up with your girlfriend in front of a company of hooligans, it is quite logical not to go where this can happen - not to stroll through the dark gateways of dysfunctional neighborhoods, not to drive her to cheap clubs and night bars. But since the meeting with the aggressors took place, it is important to behave correctly in such a situation.
Strategy
The girl is not a serious fighter, so for her in case of real danger, the best option would be to run and call for help with all her might. One way or another, but in most cases this is the only correct option. Firstly, in a fight, she can interfere, hindering the movement of a man. Secondly, the girl who ran away far away and called the police for help greatly increases the chances of her young man to stay alive and well. Indeed, in such a situation, the idea of killing and maiming the victim in the eyes of hooligans loses its attractiveness - a raid in hot pursuit will be inevitable.
Naturally, the girl should be convinced of the need for just such actions in advance, since in the event of a street fight, there will be no time for persuasion and explanation. Running away from the hooligans with her will also not work - the average girl runs much worse than a man, especially in heels.
Depending on the circumstances, you can scatter in different directions. But at the same time, the man in any way should force the aggressors to run after him. Insult them in any way or knock one of them out with a surprise blow.
You can defiantly, with loud calls to the police, to run away and the man. If some of the hooligans, fearing the involvement of the police, rush after him, the number of aggressors can be reduced around the nearest corner. Then, having found a suitable weapon (stick, stone or bottle), return and fight off the girl. If the house is not far away, you can return with quite serious weapons and help.
If there are few hooligans, they are not armed, and the girl has good sports or fighting training, she can take one of them for a while. It is advisable that she did not try to scratch his face or hang in the arms of the enemy, but struck him several good kicks in the groin. By doing this, she will greatly facilitate the task of her boyfriend to blow the brains out of both thugs.
Tactics
A normal guy needs to fight desperately to protect a girl. And if the girl, for some reason, is not able to run away, fight to the end.
First of all, you need not to panic and think carefully: what are the opponents as fighters and how far they are willing to go. The most dangerous of them should be neutralized first. A flock, left without a leader, can abandon their plans if they see that the victim is ready to go to the end and can quite realistically kill one of them.
If you have any items at hand, use them as weapons. A knife, stone, stick, bottle, belt with a massive plaque, a chair in the hands of the defender can first show the aggressors that it will be difficult for them to achieve victory, and then - increase his chances of fighting off.
If it is already clear that a fight cannot be avoided, try to hit first. The surprise factor is the best way to turn the outcome in your favor. Hit in the head, in the jaw, in the groin so that one blow is guaranteed to be enough. Watch your hands: if the enemy reaches into his pocket, immediately knock him out before he has time to get a knife or brass knuckles.
Try to think through all conflict situations in advance: at what moment and how best to attack first, what will you say to the hooligans and whether this will make sense. As soon as the fight begins, it is better to turn off all thoughts and trust instincts. Any reflections, no matter how logical and correct, are always dangerous, since they greatly reduce the speed, which is critically important at the moment. You need to think seriously and intensely only before and after a fight.
