US Marines Receives Squad Common Optic (SCO) to Identify Threats from Longer Distances

U.S. Marines recently received an innovative new optic that better prepares them to engage adversaries from longer distances. In January, Marine Corps Systems Command’s Program Manager for Infantry Weapons began fielding the Squad Common Optic (SCO)—a magnified day optic comprising an illuminated and nonilluminated aim-point designed to improve target acquisition and probability-of-hit with infantry assault rifles. The SCO can be attached to the M4 and M4A1 Carbine as well as the M27 Infantry Automatic Rifle. It will supplement the attrition and replacement of the Rifle Combat Optic and the Squad Day Optic for each of those weapons for close-combat Marines.

“The Squad Common Optic provides an improved day optic to infantry and infantry-like communities, including reconnaissance units” said Tom Dever, project officer for Combat Optics at MCSC. “It’s a system that improves situational awareness and decreases engagement times, greatly benefiting Marines.”

“Having an optic that can reach out to longer distances will ultimately make the Marine a more lethal first-shot shooter,” said Boughton. “This means they can use less rounds to overwhelm an enemy.”

SCO an improvement over RCO. The SCO enables Marines to identify targets from farther distances than the existing RCO system. The RCO has a fixed magnification, whereas the SCO provides a variable power. This means Marines can use the SCO to identify targets at both close and far distances, providing twice the visual range of the RCO. The SCO is agnostic to the round and weapon system, which provides additional flexibility for Marines. This allows for movement to a different host weapon and accommodates the employment of the M855, M855A1 or future ammunition. The SCO gives squad leaders or individual riflemen more time to make a decision to eliminate that threat if necessary.

The system is also easy to assemble. The SCO includes a mount that prevents Marines from needing to carry tools to remove or exchange the optic, lightening the load for Marines. The SCO program moved rapidly from program designation to fielding in just 16 months. After awarding a contract, PM IW conducted various user assessments, including a simulated 10,000-round fire exercise, during production verification testing to confirm performance and resolve issues. During these evaluations, Marines raved about the benefits of the SCO and its improvement over the existing system. The program office anticipates the weapon reaching Full Operational Capability in fiscal year 2022.
