>Can a weapons fag break down what’s seen in the video from a tactical and skill of use point of view?
Skill use, he was mixed. He was under high stress and made mistakes, but managed most things pretty calmly. Over all, he did well.
>Like we see him discard the 1st weapon, move to the 2nd...
As others have pointed out, the shotgun is not a fast reload weapon so he dropped it rather than try and reload. The real telling part though is that he had it at all. That is pure video game reasoning. Most of his conditioning likely comes from some variation of First Person shooter, and it shows here.
>what about his aim,
His aim was poor in most cases, but it really didn't have to be good as his targets were close and in other cases it was a target rich environment. His primary concern was to fire fast enough to hit the targets, actual aim was not as difficult. This is why you see a lot of hip shooting from him and why it worked for him.
>number of shots..
This is where stress and lack of experience come in. Many of those shots were stress shots, he kept pumping them out because of adrenaline when they were no longer needed.
Tactically this is bad because it forced more reloads, and in good example he fumbled that.
> the fumbling with the clips,
Many people don't understand how hard simple tasks are under pressure in a high stress environment. Reloads can be hard, even when they are easy on the range. That is why you should practice and condition them often. You can blame his problems on being under stress.
>reset of the weapon...etc..etc
He actually did very well here. He is obviously a very calm person naturally and was able to keep it under control in several examples, this being one of them. Even when he failed, he wasn't terrible - such as with a couple of the mag reloads.
Over all, he did very well.
