The Army is working on a rifle sight that wirelessly connects to night-vision goggles

FORT BELVOIR, Va. -- In the next 18 months or so, the Army expects to field two new systems to dismounted Soldiers that will allow for more rapid acquisition of targets, even those hidden by darkness, smoke or fog.

First out of the gate will be the Enhanced Night Vision Goggle III, expected to be fielded sometime between April and June of 2018. Shortly after, the Army hopes to field the Family of Weapons Sights - Individual, between January and March of 2019.

The FWS-I and ENVG III are unique in that the FWS-I, which would be mounted on a Soldier's weapon, wirelessly transmits its sight picture to the ENVG III, which a Soldier wears on his helmet.

Additionally, the ENVG combines thermal imaging with more common night vision image intensification technology, which is recognizable by the green image it creates.

Under starlight, targets may blend in with the background. But with the thermal capability overlaid on night vision, targets can't hide in smoke or fog, they "really pop out with that contrast," said Dean Kissinger, an electronics engineer who is currently assigned to Program Product Manger Soldier Maneuver Sensors at Program Executive Office Soldier here.

Lt. Col. Anthony Douglas, who serves as product manager for Soldier Maneuver Sensors at PEO Soldier, said the two sensors not only help dismounted Soldiers better see targets, but by paring the two wirelessly -- allowing what the weapon-mounted sight is seeing to be beamed directly to the Soldier's eye -- also helps the Soldier acquire a target faster.

RAPID TARGET ACQUISITION

"The capability gap that we were tasked with [closing] by developing this was the rapid target acquisition capability," Douglas said. "We are allowing the Soldier to actually see what is on their weapons sight, saving them time from having to bring the weapon to his eye."

Master Sgt. Lashon Wilson, the senior enlisted advisor for product manager Soldier Maneuver Sensors, explained how the system will work, and make it easier for a Soldier to acquire a target.

"This weapon-mounted system talks wirelessly to the smart battery pack that is on the Soldier's head, that then transmits a signal to the ENVG III, which now displays a reticle onto the Soldier's optic," Wilson said. "So now what this does is, while the Soldier is on patrol and he has his ENVG III on and he is looking, he has a greater field of view of what is going on in the battlefield."

Soldiers wearing the ENVG III, which is mounted on their helmet, can choose to see both night-vision imagery and thermal imaging as well in their goggle. But they can also choose to see the image coming off the FWS-I that is mounted on their rifle.

A variety of modes allows Soldiers to see in their goggle only the image from the ENVG III itself, only the image from the FWS-I, or a combination of the two. Using a "picture-in-picture" mode, for instance, the image from their FWS-I is displayed at the bottom right of the image that is coming from the goggle.

In another mode, however, if the FWS-I on the rifle and the ENVG III on the Soldier's helmet are both pointed in the same direction and seeing essentially the same thing, then the image from the FWS-I can project a reticle into the goggle. The Soldier can see the full image of what his goggle normally sees, but a circle representing the reticle from the FWS-I is overlaid onto that image, letting the Soldier know where his rifle is pointed. What this means is the Soldier doesn't need to actually shoulder his weapon to acquire a target. That saves time for the Soldier in acquiring that target.

"We are saving him three to five seconds, and increasing their situational awareness on the battlefield," Douglas said.

Additionally, because the reticle is projected onto what the Soldier is already seeing in his goggle -- a much wider view of his environment than what he would see if he looked through his rifle scope -- he is able to acquire a target while maintaining situational awareness of what else is going on around him.

STEEP LEARNING CURVE

At Fort Belvoir, members of the press were allowed to shoot an M-4 rifle that was equipped with the FWS-I, while wearing a helmet equipped with the ENVG III.

Several man-shaped targets were spaced out in the firing lane, each equipped with thermal blankets to simulate body heat. A pair of fog machines simulated battlefield smoke to make it difficult to acquire those targets using only day optics. Using night vision goggles alone, some of the targets could not be seen. But when combined with the thermal imaging capabilities built into the ENVG III and FWS-I, those targets were easily visible.

Using the system proved a bit challenging, however. When looking through the goggle, which was at one point displaying the image transmitted from the rifle-mounted FWS-I, it was hard to tell if it was the helmet that was crooked, the ENVG III that was crooked, or the shooter's own head that wasn't on quite straight.

"The gun is tilted," Wilson confirmed. He served as a trainer for members of the press who were allowed to shoot.

Maj. Kevin Smith, who serves as the assistant product manager for FWS-I, said there is a "steep learning curve," for the system.

"We just got through with the tests with the 4th Infantry Division out of Fort Carson, Colorado, back in June," he said. "We only spent about 40 hours of in-classroom training. But we also spent about a week on the range or so. That's where the Soldiers were really starting to get it and understand it and feel it, on the range."

Smith said one such training event was held at Fort Carson, and two were held at Joint Base Lewis-McChord, Washington.

"Once they get comfortable with it, they really love it," Smith said. "One Soldier, a noncommissioned officer who didn't like it at first, later on during the last test we did, asked me when are we getting this fielded. He said he wanted it now. They want to take them to war and they want to use them."

A FAMILY OF SIGHTS

The soon-to-field FWS-I is meant for the M4 and M16 rifles, and can mount on those rifles in front of day sights that have already been bore-sighted, Kissinger said. What this means is that Soldiers can pop the FWS-I onto and off of their rifle without having to remove their day sights first.

The FWS-I will also work with the M249 Squad Automatic Weapon, the M141 Bunker Defeat Munition, and the M136 AT4 Light Anti-Tank Weapon.

Kissinger said the FWS-I actually provides capability to both light and medium weapons. In the past, there had been sights fielded for both types of weapons. Now that FWS-I provides capability to both, he said, there will be less variations in weapons sights, and a smaller logistics trail, he said.

More capability is also coming to this "family" of weapons sights, Douglas said. There will be a crew-served variant and a sniper variant as well. Both are still under development, he said.

Both the FWS-I and the ENVG III are currently in low-rate initial production. The Army hopes to buy 36,000 of the FWS-I, and about 64,000 of the ENVG III, Smith said. He also said that the new gear is targeted squarely at dismounted Soldiers with infantry brigade combat teams and special operations forces.

For now, he said, he expects it'll be squad leaders and two team leaders within a squad that might first see the FWS-I.

"This is a day or night capability," Douglas said. "We're talking about dismounted Soldiers who would use this. For our mounted soldiers, those on the Stryker or Bradleys ... they do not operate without their thermal on all the time. So we are giving the dismounted Soldier the same capability the mounted Soldiers have."
