Special Weapons Daleks
The Dalek Survival Guide recorded what it deemed to be the five greatest victories achieved by Special Weapons Daleks, as well as their greatest defeats.

The Hand of Omega affair was counted as the fifth greatest victory of the Special Weapons Daleks, as a single standard-model Imperial Special Weapons Dalek (second class) was responsible for the defeat of an entire Renegade Dalek task force. The Special Weapons Dalek concerned was cited for an award for Extreme Extermination in the Face of Danger, but was unable to attend the ceremony as the Imperial Daleks were wiped out by the Hand of Omega. The late Special Weapons Dalek was instead granted a posthumous award for services inadvertently rendered by the surviving Renegade Daleks.

On MiscYam, a squadron of Airborne Daleks were mistaken for the return of the mystical Flying Gods of MiscYam legends, with apocalyptic consequences for the indigenous life-forms. The Dalek Survival Guide counted this as the fourth greatest victory of the Special Weapons Daleks.

The Special Weapons Daleks first proved their worth in battle through a "spectacular" victory in the battle of Cairtros IV. There, General Arthur Brook had no intelligence information about Special Weapons Daleks. Long range scans indicated the presence of 50 Daleks. Brook allocated a force of 300 men, thought sufficient to take care of such a small force of Daleks. On landing, the 300 men were reduced to zero in less than five minutes. The Dalek Survival Guide counted this as the third greatest victory of the Special Weapons Daleks. In its aftermath, the Dalek Emperor ordered the full-scale reproduction of the Special Weapons Daleks.

On the jungle planet of Junglos, a mere four Airborne Special Weapons Daleks kept an entire division of troops confused and besieged in the tropical jungles for months. The troops eventually ran out of rations and died of starvation. The Dalek Survival Guide counted this as the second greatest victory of the Special Weapons Daleks.

On the planet Steraxius, a flotilla of Torpedo Daleks posed as a shoal of beached water mammals in distress. As the Steraxian Ecological Foundation operatives approached them, the Torpedos opened fire, devastating a large proportion of the planet's defenses and leaving it open to Dalek conquest. The Dalek Survival Guide counted this as the greatest victory achieved by Special Weapons Daleks. (PROSE: Dalek Survival Guide)
