The rifle class consists of many weapons from multiple countries. The rifle class, both standard and bullpup, include the M4, AK-47, Steyr Aug, TAVOR, L85, and ACR Masada. These are the workhorses of your squad.
With the longest range, the sniper rifle class can hit targets over 1000 feet away. With either semi-automatic and bolt action, they are incredibly effective at range, especially since they can eliminate targets with one shot.
