It's not easy but it's not the hardest either.
I think we're getting too used to hard mode that aren't hard at all.
For elite Radec I used the flamethrower as soon as I got my hands on it and I brought a shotgun to the upstair section too, that helped a bunch...
PS : you kill the rocket launchers guys before getting to Radec, not sure what the other poster meant...
I sniped two and then there is a cutscene and you can reach the others( some flying vehicle crashes through the window). I killed them with my shotgun ( charge and shotgun works well, headshot shotgun is still one shot kill in elite).
Flamethrower was very handy for the grunts that come to the balcony before the rocket launcher guys...
Personally I found out CoD:Waw hardest mode to be a lot more cheap than KZ2 with the constant grenade spam...
