AI hit chance?

What is the chance for AI to hit? I understand it increases every shot, but do they always miss their first shot no matter what the range? It’s a little bit weird to see a trained soldier miss a stationary target 30 meters away.

Also, do the AI have better bolt accuracy? I’ve been noticing my 1903 AI get more kills than my Garand AI, but Brownings and M2Cs top the kill list.

First and second shot most of time miss the third one is a headshot with every weapon, this is most common to see wit manual/semi-auto, but is present even in automatic weapons

AI accuracy seems to be affected by weapon dispersion and tend do best with accurate high RoF weapons. They also seem to have different engagement ranges so bolt action armed infantry will engage enemies at a further range than guys with SMGs.
