 A DEAD mission can be planned against enemy air defenses. Its purpose is to destroy enemy air defenses. The flight will rendezvous with the rest of its package and aim to have weapons on the target at the package's TOT. After releasing its weapons, the flight will RTB.
 
-**Note for DCS Liberation 3.0:** DEAD loadouts may now differ from SEAD loadouts, and SEAD is now the preferred mission type for suppressing SAMs with HARMs or decoys. When picking loadouts for DEAD missions, prefer bombs and missiles that can kill every unit at the target, not just emitters.
+DEAD missions are typically planned in coordination with a SEAD flight when then the target is a radar SAM. The SEAD flight will suppress the target with decoys or ARMs while the DEAD flight ensures the kill with bombs and ATGMs.

 ### SEAD
 
-A SEAD mission protects other flights from SAMs. In contrast to DEAD, it will engage air defenses near the target area and not just the target itself. The flight will rendezvous with the rest of its package and begin to search for and suppress any enemy air defenses within a predefined range. After releasing its weapons the flight will RTB.
+A SEAD mission suppresses the package target. This can be accomplished with decoys or ARMs.
 
-**Changed in DCS Liberation 3.0:** A SEAD mission suppresses the package target. This differs from DEAD in that the destruction of the target is not a requirement for mission success. An F-14 using TALDs to prevent the target from destroying the DEAD flight delivering bombs to destroy the target has accomplished its mission. An F/A-18 using HARMs to keep the SAM turned off while the DEAD flight delivers bombs has accomplished its mission.
+In contrast to DEAD, its goal is not to score a kill. SEAD flights employing HARMs might kill a radar, but that isn't required for mission success. The objective for the SEAD flight is to keep the target's radar off (or occupied, as is the case with decoys) so the DEAD flight can score the kill.

+The flight will rendezvous with the rest of its package and fire its weapons (or decoys) at the package target once it reaches its IP. After releasing its weapons the flight will RTB.
 
 SEAD flights will be planned to accompany DEAD packages. When the SEAD flight uses HARMs it is quite likely that they will destroy the emitters (when not using Skynet), but they will never kill launchers/TELs without their own radar. DEAD will often carry bombs rather than ARMs or decoys so they can destroy the non-emitting parts of the SAM as well.
 
 **Note:** SEAD flights have a ToT 1 minute ahead of the rest of the package.
 
-### SEAD Escort
+A player performing this mission is expected to fire HARMs in PB mode so that the weapon's TOT roughly aligns with the package's TOT, even if the emitter is off. It is best to fire HARMs one by one, staggered by a minute or so to keep the site suppressed for as long as possible, always trying to keep one HARM in flight near the target. When using decoys rather than ARMs the principle is the same, but you'll just have to guess at the decoy's TOT.

+### SEAD Escort
 
 A SEAD escort mission protects any other flights that are requesting an escort from SAM threats. Flight plans that pass within the range of enemy SAMs will request a SEAD escort. A SEAD escort will fly a flight plan similar to the rest of the package while engaging detected SAMs near the flight path and will then RTB.
 
-This differs from SEAD by engaging *any* SAM threating the package between the join and split points rather than only the package's target.

+A player performing this mission is expected to fly the route while searching for SAM threats (using TOO mode for the Hornet, HTS for the Viper, etc) and engage any emitter that begins to threaten the package.
