The OI is a hailing and warning device, and is more widely known as the GLARE RECOIL. This system provides an eye-safe laser that can be handheld or mounted on weapon systems equipped with a Military Standard-1913 rail attachment bracket. The system visually obstructs targets by producing a glare effect and is effective from 10 to 500 meters. Employed for Escalation of Force (EoF) situations, the OI is intended for use as an unmistakable visual warning capability to attract the attention of personnel approaching lethal force authorized zones, with an inherent function to visually suppress potential threats as the situation dictates.

The intensity of an OI effect is correlated to the size of the visual field obscuration angle, which is proportional to the irradiance of incident light in relation to the ambient background illuminance. If a warning at 500 meters does not produce the desired result (e.g. slow down, pay attention to the traffic cones, and heed the warning), stronger effects may be delivered until voluntary compliance is achieved or friendly forces can close and/or address the target with different means. For individuals at closer ranges, the desired behavior is achieved if the targeted individual ceases movement towards the OI user.

With the ability to adjust the beam divergence, the operator can vary the size of the spot to better match the tactical situation. When employed at ranges between two (2) and forty-one (41) meters (entry control points, crowd control, urban patrolling, cordon and search, and clearing facilities), the operator can increase spot size to aid in targeting individuals; at distances beyond forty-one (41) meters, the operator can focus the divergence, allowing a greater concentration of energy, yet still achieve an effective spot size on a target at 500 meters (vehicle check point, convoy security, perimeter security, and urban patrolling).

Operational Impact

Based on recent operational experience within the Marine Corps Forces Central Command Area of Operations, targeting a person’s vision was assessed as the best solution to satisfy capability gaps associated with EoF scenarios while mitigating inadvertent lasing. Both a vehicle operator and an individual navigating on foot require visual contact with their surroundings. When one’s sense of vision is affected with an unambiguous visual warning, or temporarily degraded so that visual navigation is impaired, a safe standoff can be achieved. This provides a physiological solution and reduces the risk of miscommunication or non-recognition of intent, due to differences in tradition, or widely accepted ways of behavior specific to a society. This directly benefits Marines by reducing the need to exercise lethal force, increases safety for friendly forces and indigenous personnel, and provides effective deterrence against unauthorized vehicles and personnel, enabling Marines to utilize a response of varying intensity, and increases civilian population awareness of security areas.

The OI Dazzling Laser is intended to replace the Marine Corps’ current inventory of dazzling lasers (LA- 9/P and the 532P-M GLARE MOUT). Naval Forces (Navy and Marine Corps) will employ the OI Dazzling Laser globally across the range of military operations.

Program Status

The OI is currently in the production and deployment phase of the acquisition framework. Initial operational capability is planned for February 2019, with full operational capability being achieved by October 2021.
