They are testing a new high-tech sound direction-detection system.
Imagine a small recon unit of Army soldiers was advancing through hostile terrain on a high-risk scouting mission to find points of entry for a major follow-on armored ground assault. What if it was suddenly hit, even overwhelmed, with a massive array of enemy small arms fire? The soldiers take casualties, run for cover and immediately engage the enemy, yet the attackers are obscured from view. Where exactly is the enemy fire coming from? What if soldiers could immediately know the source of incoming fire?
Perhaps a sniper is, by design, hidden in leaves, brush or other kinds of camouflage? Wouldnt it be useful to destroy the attacker before more soldiers were hit? If a small area of attacking fire were precisely identified, perhaps the recon unit could call for immediate air support to blanket the enemies with suppressive fire from above?
These prospects are now a reality.
Traveling at supersonic speeds, a bullet exiting a gun barrel generates acoustic shock waves propagating through the air from the tip of the projectile, producing a sound signature which can be detected by specially engineered sensors, according to Raytheon BBN engineers.
This technical process, simply put, saves lives as it enables soldiers to instantly know the exact location of incoming enemy small arms fire, offering an opportunity for a precise and lethal counterattack amid high-intensity combat. A technology which does this, made by a Raytheon subsidiary called BBN, already exists and has been deployed with U.S. Army soldiers. Its called Boomerang, and a set of six different sensors can instantly find the source of incoming bullets from moving vehicles and stationary locations.

I was going to ask if they were fried in vegetable oil or peanut oil? LOL.
Pork fat!
Yeah, I’d like to know where the ones that hit me in Nam came from but I have a good idea they came from an NVA soldier!!
Thank you.
Pedantic firearm nomenclature nazis are annoying.
Now I'm going to go buy some new clips for my assault rifle.
You seem like a nice guy...lets agree they probably can from the NVA. Lol.
We have several other Purple Heart recipients here on FR who also 'won' these medals in Nam.
No, actually they want to know where fried bullets are coming from.

do you take yours with catsup or maple syrup?
“Until were the bad guys.”
Exactly.
I tell ya, Autocorrect has me on the wart path.
I mean, I’m really starting to latte Autocorrect.
Odds are, but sometimes not.

Be sure to avoid the fried bullets
Those that do not learn the lessons of history are condemned to repeat them.
Actually, this type of problem was solved in WW1 by the Allies. They used both listening posts in no man’s land connected with telephones to commanders along with “flash” observers on the front trench lines. Then it was a few minutes with maps and trig function tables and they knew where the enemy was. They were quite good at locating and calling in artillery fire on enemy machine gun and artillery positions.
Obviously, a few spaced bullets are harder than long bursts of machine gun fire or the loud report of a cannon. However, modern infantry warfare mostly uses assault weapons and rocket propelled grenades, so it is not all that different. Besides we have computerized microphones, thermal sensors and photo sensors that can be linked on the battlefield.
Mmmmmm...bacon....

I remember thinking, for a very brief moment, how cool green tracers (from NVA AK-47s) looked coming at me once night. Then I came to my senses and gave him a chance to ponder the beauty of orange tracers coming at him!
Ears. They pick up sound waves and send signals to the brain to determine from which direction the sound is coming. The determination can be augmented by visual clues sent from eyes and validated/ corrected/ refined by auditory input from other soldiers with ears. Usually, it’s extremely accurate. Usually.
The Maneuver Battle Lab ran an assessment of the Multimodal Hostile Fire Detection (HFD), also a BBN initiative, this past August. The HFD adds an IR sensor to triangulate the crack of the shockwave, bang of the shot, and flash from the muzzle. The system worked well against short range, unsuppressed weapons, but not so well against longer range, suppressed. Promising technology, but still needs some work to provide an instant, precise point of origin of the shooter, just my opinion.
Fried, fired, same thing. ;)
Example:
Let’s go out to the range and fry some bullets. ;)
