Electronic Warfare: What US Army Can Learn From Ukraine

he US military has for weeks been training Ukrainian forces in US tactics, but the commander of US Army Europe says Ukrainian forces, who are fighting Russian-backed separatists, have much to teach their US trainers.

Ukrainian forces have grappled with formidable Russian electronic warfare capabilities that analysts say would prove withering even to the US ground forces. The US Army has also jammed insurgent communications from the air and ground on a limited basis, and it is developing a powerful arsenal of jamming systems, but these are not expected until 2023.

In CMANO, expect for the mobile jammer units (which as far as i know only jam radars), would there be a way to simulate this ?

Have you ever considered a unit going "autonomous" (kind of like an allied unit) to simulate broken/jammed com link between the player (acting as the commander) and the unit on the ground ?

I was reading some tweets from a guy on twitter the other day...some professor, or professional in the defense industry, and he was pretty much saying this same thing. Russia's Electronic Warfare is very mature and advanced, and far better than what the U.S. or any NATO member can output currently.

Only stands to reason that, if your primary peer adversary relies on certain technologies as their main force multiplier, then do all you can to deny them that. We went all in on satellite systems, and they are doing all they can to disrupt that.....I knew we should have also invested in bears.....can't jam a bear... :)

You just can't be too careful with Bears!

Funny article
especially :
"The US provided Ukraine with lightweight counter-mortar radars in November 2014, which Hodges said its troops have "used in ways we have not used it ourselves, and made it more effective than we thought was possible."

there is four of this systems, one lost on way to frontline ,two captured by Novorossian Armed Forces in Debalcevo (they was even not assembled) . It seems Lt. Gen. Ben Hodges is man with great sence of humor.

overall article is strange , "OMG,SHOCK Russian SUPERUBERWUNDERBAR EW systems not only exist, they destroy half broken, half never work, 25-30 years old command and control network of Ukrainian Army"

Navyrecognition idea about unit going "autonomous" is interesting, actually it can be used to correctly divide those submarines that have "Noks-NKS" and similar systems from submarines that can not , while submerged, communicate with aircrafts and satellites if they dont deploy antennas above surface(in case of submarine with Noks-NKS obviously there is no need to deploy antennas to surface, Noks-NKS create secure datalink between submerged submarine and Navy, exactly as in CMANO )

When I was active duty, I argued all the time that our drone systems would likely get neutralized on day 1 of a real shooting war with a stand-up enemy (ie not ISIS or any of the other 7th century AD forces we seem to think we'll be fighting forever to the exclusion of all else).

I guarantee the Russians and Chinese have made it their #1 priority to research how to disrupt and degrade our increasing reliance on remote/drone systems. And they would not reveal such a capability until they needed to do so.

Let's hope that never happens, and let's also hope they can get those mothballed A-10's and F-16's out of storage real fast. They'll need 'em.

^ That's why next gen weapon systems in the works like LRASM can go autonomous in case of lost datalink I guess

Most UAV's can already go autonomous. Some crash, some fly to a programmed area. Its being hacked and forced down or even turned on you that can be the real issue.

In regards to preparation against 1st rate space capable adversaries, I'd recommend any articles you can find about the U.S. 527th Space Aggressor Squadron out of Colorado at Schriever AFB. As well as the 26th Space Agressor Squadron.


"We replicate what it would be like if an adversary fought back and tried to take away the force enhancement capabilities from the warfighters," said Crimm. "This may include communication, GPS or any space systems that we could use to leverage against the enemy. Our aggressors will try to take those away from the blue forces in an exercise environment."

During those exercises, the 527 SAS conducts adversarial tactics including jamming satellite communications and GPS receivers in an attempt to teach the warfighters the effects of the adversaries' weapon systems. The blue forces then attempt to mitigate the problems associated with these tactics.


"We ask them before we begin 'How much pain do you want?' " the lieutenant colonel said. "We're not out to wreak havoc on them just for the sake of wreaking havoc. We want to show them what they're likely to realistically encounter. As a squadron, we will only play within the certified boundaries of what we know the opposition's tactics and capabilities are. We can replicate any adversary with space capabilities. And if we do it correctly, blue forces will build countermeasures for air and space superiority as the commander has intended. It makes for a more efficient and effective force."


WASHINGTON (Reuters) - The U.S. Air Force quietly has put into service a new weapon designed to jam enemy satellite communications, a significant step toward U.S. control of space.

The so-called Counter Communications System was declared operational late last month at Peterson Air Force Base in Colorado Springs, the Air Force Space Command said Friday in e-mailed replies to questions from Reuters.

The ground-based jammer uses electromagnetic radio frequency energy to knock out transmissions on a temporary and reversible basis, without frying components, the command said. "A reversible effect ensures that during the time of need, the adversary's space-based capability to threaten our forces is diminished," said Capt. Angie Blair, a spokeswoman. "Following the time of need, the space-based capabilities used by the adversary can return to its original state."


Jammers have shown their efficiency in the Iraq war in 2003 [9] by jamming Global Positioning System (GPS) receivers. In general, a jammer has large operating range, e.g., a GPS jammer made by the Russian firm Aviaconversia [10] is claimed to have a 150 – 200 km operating range. The basis of a jammer is that the jamming emitter transmits signals falling in the target receiver’s working bandwidth, whose power is much larger than the target receiver’s desired signal, and therefore, the target receiver’s desired signal is flooded by the jamming signal. Actually, all the receivers are possible to be jammed, and the receivers with high sensitivity are more vulnerable to jamming, e.g., GPS receivers, radar receivers, and communication systems.

Anti-jam techniques include spread spectrum [11], smart antenna technique [12], and localizing and destroy. In the spread spectrum technique, the desired signal is spread over a wide frequency band via direct sequence spread spectrum (DSSS) or frequency-hopping spread spectrum (FHSS) method. If the jamming signal is narrow band, in the de-spreading process, the jamming signal would be pressed and the jamming effect is alleviated. In the system that applies antenna technique to compete with the jammer, a smart beam pattern is generated to achieve a maximized signal to jamming ratio by directing the lowest antenna gain to the jammer. The de-spreading gain and the antenna’s directionality are limited. For example, (1) GPS C/A code includes 1024 bits and the processing gain is about 30dB, if the jamming signal is larger than the GPS signal 30dB or more, the GPS receiver would be totally jammed. (2) The signal to jamming ratio that a smart antenna can mitigate depends on the smart antenna’s beam pattern, which is determined by the number of the elements in the smart antenna (which is limited by the array size), and the number of jammers and their distribution. When the jamming transmitter’s power is enhanced, the efficiency of the spread spectrum and antenna technique would fade. On the other hand, a jammer with higher power would be easier to be localized. When the jammer is localized w ith high accuracy, we can either avoid it or destroy it.
