I've done a search on A&M Complete and have found no mention of this addon, so I thought I'd draw your attention to a news item on flashpoint.ru.
ORCS have produced a v2.0 of their "Special Effects and RD54 Backpack" addon - available here.
From the readme (I've not tried it myself yet), it lists:
-=Effects for tanks=-
(detonation, burning, flame from the barrel)
(burning, in-water & on-ground detonations, smokes)
(in-water & on-ground detonations, )
(demo version of detonation)
-=False thermal targets=-
(for helicopters, russian and NATO planes)
For using by AI:
- for helicopters
- for russian planes
- for NATO planes
-=Bomb "Voron" for Su-25 plane=-
-=Effects for people=-
(RPG and rifle smoke)
- plus what appear to be basic, medical, engineer/sapper and empty versions of the RD54 backpack.
Mme Avon will doubtless be delighted to hear that there is also a demo mission - requires ICP_RFWP 3.0 pack
