Jamming is a very inexpensive tactic as the software is relatively cheap and it can take out munitions worth tens of thousands of dollars, Defense One reported.
You know what can't be jammed? An artillery shell. Armed with that knowledge I am confident the West will continue dumping money into wunderwaffen
Except some of them can -- some of the US shells use GPS and whatnot to help guide it to the target.
But also the latest "aid package" to Ukraine gave them less than a full day's worth of artillery shells. The US is getting fully tapped out.
