The OOS-3G2 is a third-generation optical sight for the Tolesian military. Designed to be rugged, flexible, and straightforward, it combines a comfortable sight picture with a small magnifier and iron sights. The tricky thing about its development was balancing the size of the optic with their soldier's needs. Ultimately designs that were more practical to their biology were fragile, so the emphasis was on tailoring the optic work with their vision. However, it required soldiers to focus through the aperture. The result was a practical design that was easy to make and compact on the weapon but was slightly frustrating for soldiers to use.
