suggestion: in the case of whoever set the sams being smart enough not to set the sams launch at max range, it is wiser to not fly directly towards the sam. If you fly slightly to the side (say 30 degrees or so) the sam has to fire the missile away from you to intercept your course. When turning away from this scenario, the missile will have to spend huge amount of energy to adjust itself instead of flying straight after you
One more tip: OSA has limited minimum altitude. This means that when going very low it should trigger the missile fuze by ground clutter. Not sure how its implemented but i noted that when flying very low with Ka-50 it won't even fire at me allowing me to take it down with VIKHR. Flying low also decreases its range as missile has to fly trough dense atmosphere making it more draggy. This effect was very notable in medium and long range SAMs, SA-5 used special flight profile with a kind of top attack which made missile fly high and then descend to target, this was to maximize effective range by avoiding dense atmosphere during thrusting. IIRC one of reasons that led to Tunguska design was problem with SA-8 minimum altitude making it not so effective against helicopters. Tunguska was designed to blast low hovering helos so they made RPF less sensitive and they decided to use EO tracking for both the target and missile. Radar in Tunguska was used to do target acquisition and ranging, but not for tracking.
SA-8 carries 6 missiles in most variants. IIRC only earliest variants carried 4. AFAIR DCS implements OSA-AK variant with ~11km range and 6 missiles carried. OSA has 2 missile and 1 target clannel which means it can guide 2 missiles at once against single target. Second thing is chaff/flare, if you do this too early it don't gonna help, and flares won't help at all OFC. When missile is far from you using chaff is a waste because what chaff is intended to do is to trigger premature detonation of radio proximity fuze. In this case when you start to litter early chaff gonna hit the deck before missile reach you, it won't help so much this way. So start chaffing a little later, when missile get closer, this way you gonna save some chaff.
Chaff creates a radar signature to confuse the missile. Dropping it earlier means that the radar has less resolution to tell which radar signature is which.
Interesting to watch, generally a Viggen will defeat threats like an SA-8 "Gecko" kinematically- that is by using its raw performance to run the missile out of energy
There has to be some trees on a flat plain, especially for those plains in the dcs. I prefer to use these trees as mountians and hills to duck behind. If you are a skilled ground skimming pilot, you can even beat an s300 site by this way.
Basically yes but you might need to adjust tactis sligthly depending on how modern the SAM is. The patriot is very difficult unless you manage to terrain mask. :)
Creative Fun I've managed to kill SA-10 in a flat land on the Nevada, terrain masking until 20km of the Sam, then there was no terrain, no trees and no building. The SA-10 must be the most dangerous threat. It has a superior range and more importantly, your RWR can't alert you when the SA-10 have fired a missile. You can't have a Missile Launch Warning against the SA-10 (I don't speak for the Viggen only, but for any aircraft, no RWR can distinguish a SA-10 launch)
