Assault Rifles are all purpose, flexible weapons that just get the job done. They are at their best at medium ranges, but can be modified with attachments to perform better at shorter or longer distances. ARs have average mobility, ADS time and good bullet penetration.
Fully automatic ARs are effective at close to medium ranges, while burst-fire and semi-automatic are very strong from medium to long range.
