How to unlock the Sitting ducks achievement in Tom Clancy's H.A.W.X. - Definitive Guide
This will require perfect timing, your opponents to be at a low altitude. This can be boosted too, but to make sure that boosting it will work, make sure to save your EMP every time it is earned. Then lower the opponents health and make them go to a fairly low altitude. Activate the AA missiles then the EMP, this is because the EMP is quicker than the AA missiles. The health needs to be below 30 and the altitude below 1000.
