The other half of this story would be the AGM-45, AGM-78 and maybe even the AGM-88 (1985) anti-radiation missiles.
I guess the Sidearm on the Harrier is sort of a proxy for the AGM-45 but the AGM-78 has been around since 1968 and we have nothing like it for DCS. Also I believe the US used dedicated chaff bombers (dropping large amounts of chaff at high altitude) extensively in Vietnam to degrade the SA-2's performance. Sounds like a good job for the AI.
