The DIRCM on the Mi-28 NM doesn't seem realistic. I don't think dazzlers would actually be effective on IR-based SAMs because lasers lose energy at long range, due to atmospheric interference and beam divergence; a small laser is probably only effective at short distance. Moreover, the IRIS-T missiles in question here use a radar-based proximity fuze so it wouldn't just fly past its target even if a laser completely blinded it.
