You might be out of your lane on this one. The RF and IR jammers on the CV are very capable. There is a handful of threat systems I'd happily fly through the WEZ of (and have at China lake/Nellis etc). Plus others are easier to mitigate with supporting assets due to the speed of the V-22 and decreasing vulnerability windows.
The CV-22 is the most capable vertical lift platform in the world when it comes to high end threat pen. Yes, even including the 160th and I'd stake my reputation on that.
No, pretty sure he ain't out of his lane. As irascible as he may be saying that to Brett is like arguing the technicalities of traffic law with a state trooper and the judge in traffic court, and I've been to traffic court enough times to know that doesn't end well for the defendant.
I'm something of a EW/EA hobbyist myself and can say pretty confidently that however capable the V-22 might be it would be a mistake to think it is survivable against many of the more modern SAM systems that are fielded nowadays.
