Night Vision: Active Aiming vs Passive Aiming
When shooting under night vision, there are two fundamental aiming methods: active aiming using an infrared laser, and passive aiming through a traditional optic. Each approach has distinct advantages and limitations, and understanding both is essential for anyone building a night vision shooting system.
Active Aiming with an IR Laser
Active aiming uses an infrared laser aiming device to project a dot onto the target. The IR laser beam is invisible to the naked eye but clearly visible through a night vision device. The shooter simply places the laser dot on the target and fires. Popular IR laser devices include the AN/PEQ-15 (ATPIAL), DBAL-A3, MAWL, and various civilian-legal alternatives.
The primary advantage of active aiming is speed. Because you do not need to align your eye with an optic's eyepiece, you can shoot from a wider variety of positions, including around barricades, from unconventional stances, and during movement. Active aiming also allows for a more heads-up posture, maintaining better situational awareness of the surrounding environment.
The main disadvantage is that using an IR laser emits energy that can be detected by an adversary who also has night vision. In a tactical context against a near-peer threat, this is a significant concern. In a hunting or recreational context, it is generally not an issue.
Passive Aiming Through an Optic
Passive aiming means looking through your weapon optic while wearing a night vision device. To do this, the optic needs to be raised high enough that you can look through it while the NVG is mounted on your helmet. This is typically achieved with a high-rise optic mount, such as the Unity FAST mount or a 1.93-inch height mount.
Red dot sights and holographic sights with night vision-compatible brightness settings are the most common optics used for passive aiming. The red dot or holographic reticle is visible through the night vision device at its lowest brightness settings, providing a traditional sight picture without emitting any detectable energy toward the target.
The advantage of passive aiming is that it is completely covert. There is no laser beam to give away your position. It also eliminates the need for an IR laser device, reducing weight and cost on the rifle. For shooters who already have a quality red dot or holographic sight, the only additional investment is a taller mounting solution.
The disadvantage is that passive aiming requires a consistent cheek weld and proper alignment behind the optic, just like daytime shooting. This limits the positions and angles from which you can effectively engage targets, and it is generally slower than active aiming, especially at close range or during rapid transitions.
Combining Both Methods
Many experienced night vision shooters run both systems simultaneously: an IR laser for close-range and fast engagements, and a raised optic for longer-range shots or situations where covertness is required. This combined approach offers the most flexibility but also adds weight and complexity to the rifle setup.
The key is to train with both methods so you can transition smoothly between them depending on the situation. Active aiming for fast, close-range work. Passive aiming for precision shots at distance or when you need to remain undetected.
Equipment Considerations
- IR lasers: Full-power military devices (AN/PEQ-15, MAWL) are restricted to law enforcement and military. Civilian-legal alternatives are available at lower power levels.
- Optic mounts: 1.93-inch height mounts (like the Unity FAST or Scalarworks LEAP) are the standard for passive aiming under NVG.
- Optic compatibility: Not all red dots and holographic sights have night vision brightness settings. Verify before purchasing.
- Helmet setup: Both methods assume the NVG is helmet-mounted, not handheld.
