Radar is tricky, as we can't do what Radar really does, or jam it the way it is really jammed, but...
for the most part, Radar sees the RCM plane as if it is a Squadron , so it can be used to decoy, the enemy (some planes, really did this, they were set up to toss out chaff, that looked like aircraft, and one use, was to jam a area, with a simi Known raid flying towards the jammed area, then once in the jammed zone, turn towards the target heading, and stay with in the jamming, while others would fly into a decoy path, trying to look like the full blown raid, hoping to draw in the defenders to the wrong part of the sky, hoping there small numbers would make them HARDer to find)
best uses ? depends on the player, depends on the enemy
single planes can be used for spot jamming, a stream of elints can look like a raid, a stream of jammers, can knock out radar along the whole path of the mission, once you have enough (never enough) you can send out a stream to either side of the Main force raids, with singles going to key radar sights, with some long legged streamers, flying with and after the Main force
one thing is, it is a chance, to jam, it is not, it will jam, so, more planes in the area, trying to jam, got a better chance of getting the job done, so, while you can plot single plane missions, it may be better to at least fly in pairs, or triples, staggering the target points a little bit
window is a short range jammer, it jams, by flooding the radar with as many targets as there is chaff in the air, but, it was breakable, if you knew how to read the data coming in, and later German Radar, was not as prone to falling for it, so the other jammer types are improvements to the system
(on a side note, the US after the war, wanted to know what the Germans thought about the P-61, they told them they wern't worried about it, when asked why, they told them, the pilots didn't fly like Germans, so they always knew from the ground where they where at and when they were in the area)
