“The Homer” is best compared to the M2 Bradley, whose development process was described in the book (and later movie) “The Pentagon Wars”. Unfortunately, all large combat systems (most notably ships) tend to come with a grab bag of ‘features’ of varying utility.
The M2 Bradley is an amazing vehicle, which does not accomplish the goals which its development program started with (basically a low-cost and reliable armored personnel carrier). This is why the M113 is still in service.
They may be referring to the campaign Burton waged against the Bradley's testing program.
Basically he wanted the Army to do a bunch of tests we already knew the outcome of: that the munitions in question would defeat the armor. This wasn't some sort of scandal or surprise to the pentagon. No armored vehicle is invincible, and the Bradley is already as heavily armored as is practical to cross bridges without them collapsing, etc.
Burton made a ton of enemies treating this like some sort of huge scandal he was uncovering, but in reality he was distorting the situation, then used it to popularize his book.
Basically he's just a grifter, but because he was saying contrarian things a bunch of people who had no idea what was actually happening bought into his bullshit.
It's similar to what happened with the "Fighter Mafia" where the public latched onto it without understanding how utterly bullshit the contrarian proposal actually was.
