Question about The Ancient Gods (Doom Eternal) expansion

Hello, a question about the Marauders from The Ancient Gods expansion. In the original game, I calmly killed them in this way:



I stunned them, launched a rocket, then a grenade, guidance and a triple volley from a rocket launcher, after such processing it was easy to finish off the marauder. In addition, this method does not work? In the main game, such a "trick" worked in 70-80% of cases, in addition for half a hundred attempts it never worked.
Tell those who played on the nightmare, is it possible at all to hit the Marauder with three rockets in additions?
