Called the Fire Control Unit, the Office of Naval Research sent out six prototypes of the mortar sight that attaches to the weapon's upper barrel. A Marine chief warrant officer made the request to ONR in hopes of improving accuracy.
One assistant mortar instructor said it's especially valuable at night.
“The nighttime capability is awesome, I mean awesome,” assistant mortars instructor Sgt. Garrett Dennard said in the statement. “At night, by the second round, I trusted it 100 percent.”
ONR officials also worked on a solution to make it easier to transport the mortar by developing a sling and heat shield that protects a Marine's hands. The has a lightweight mount to eliminate the "loud clanging that the old mount made when it banged against the weapon in transit, which could give away a Marine's position," according to a Marine statement.
“The new sling and sight overall are really important additions to the weapon,” Dennard said in a statement.
ONR's TechSolutions worked with L3 Insight Technologies to build the sight and Tactical Assault Gear Industries to build the sling and heat shield.
