- "Can you score 25 unassisted kills-using only your weapon- with no Pointstreak assistance whatsoever?"
- — Call of Duty MW3: Official Strategy Guide description
The M.O.A.B. (Massive Ordnance Air Blast, nicknamed Mother Of All Bombs) is a hidden 25 kill-streak (24 with Hardline) reward featured in Call of Duty: Modern Warfare 3. The M.O.A.B. is obtainable with any Strike Package.
The M.O.A.B. is similar to the Tactical Nuke Killstreak seen in Call of Duty: Modern Warfare 2. It is earned by getting a 25 kill streak (24 with Hardline), not including kills achieved through Pointstreaks (i.e. the player can only use guns, equipment, and melee). Also, unlike with the pointstreaks in the Support Package, the player must not die in order to obtain M.O.A.B. Unlike the Tactical Nuke in Call of Duty: Modern Warfare 2, its detonation won't end the game, but will kill every enemy player who is alive when it is called in. The blast also causes an EMP like effect, called a M.O.A.B. fallout, to go off, eliminating all enemy equipment, electronics and pointstreaks (except ballistic vests) for one minute.
A player that calls in a M.O.A.B. will also unlock Double XP for the remainder of that match for their entire team. The explosion litters the map with dust and a red tint that remains for the rest of the game, similar to the Nuke effect on the map, even if another M.O.A.B. is called in.
If another M.O.A.B is called in by the enemy after a friendly one has gone off, the first team who called it in will lose double XP upon the second team gaining it.
- If there is a M.O.A.B. activated and the host leaves the match, the red dust will disappear from a player's screen until he or she dies and respawns.
- In the Wii version of Call of Duty: Modern Warfare 3, the M.O.A.B. does not have the same countdown sound as the PlayStation 3, Xbox, or PC version of the game. The M.O.A.B. countdown on the Wii sounds exactly the same as the Tactical Nuke from Call of Duty: Modern Warfare 2.
- Players who have not unlocked the "Fallout Shelter" challenge will be awarded the "Toxic" callsign title after dying from a M.O.A.B., similar to Call of Duty: Modern Warfare 2 where one was given the same title name when killed by a Tactical Nuke.
- There is a callsign title in Call of Duty: Modern Warfare 2 called "MOAB" unlocked after completing the "Ultimate Sacrifice" challenge.
- When a M.O.A.B. is used in the killcam, it will show the M.O.A.B. owner's first person view.
- When viewing the killcam after being killed by the M.O.A.B., the map will always appear with the red tint the M.O.A.B. creates, even if it takes place before the detonation.
- There are challenges for getting the M.O.A.B., but they cannot be viewed in the Challenges section.
- The acquisition sound for the M.O.A.B. is the same as the Tactical Nuke.
- It is possible to acquire a M.O.A.B. on the community playlist game modes Drop Zone and Infected, even though it is sometimes set for no killstreaks enabled on Infected and always set for no pointstreaks on Drop Zone. This may be because the M.O.A.B. is a hidden killstreak seen on all strike chains.
- At the end of a game in which the M.O.A.B. was used the music will be a low drum noise, regardless of if your team won or not.
- This music is also used as the Special Ops menu music.
- When a recent game involving a M.O.A.B. is viewed in Elite, the killfeed will show the player as getting a "Nuke" and the Tactical Nuke image (Create-a-Class Image) will appear next to it.
- Unlike all of the other pointstreaks, the M.O.A.B. streak does not reset. That means that the player needs to die in order to reset the streak and get another M.O.A.B.
- The sound effect of the M.O.A.B. going off is also used in the "Shock and Awe" flashback in "Blood Brothers".
- On the Wii version of MW3, if a team calls a M.O.A.B. and it must kill four or less players to win in TDM, it is possible, for some enemy players, to survive to the explosion. As with tactical nuke, the closest players to the detonation zone will die first.
- One can survive a M.O.A.B. if going into Final Stand mid-explosion.
- Strangely, the M.O.A.B. will not destroy Tactical Insertions.
