Their operations involve undercover missions to monitor Four Emperors activity. Koby and X Drake were shown contacting each other to discuss urgent developments. SWORD uses code words to verify secure channels.
| X Drake
Although the current strength of the group is unknown, the accomplishments of its members are notable.
- X Drake: Captain of SWORD and former Marine Rear Admiral, formerly undercover as a member of Kaidou's Beasts Pirates, and an infamous member of the Worst Generation. Within two years of joining Kaidou's crew, Drake was able to become a member of the Tobiroppo, a group that is considered the strongest of the Shinuchi.
- Koby: Marine Captain and an important figure during the Rocky Port Incident, who had also been deployed to arrest Boa Hancock.

Wano Country Arc
X Drake contacted Koby from Wano Country to debrief him on the progress of an unknown mission. He also updated Koby on Kaidou and Big Mom's alliance. Drake revealed that CP0 was also present in Wano, to which Koby reacted with shock and foreboding.
- Their name, SWORD, contrasts them with CP0, whose full name is Cipher Pol Aigis Zero. The word "Aigis" comes from the word "Aegis", meaning "Shield" in ancient Greek.
- SWORD's method of sending Marine agents to infiltrate notable pirate crews is similar to when Commander Donquixote Rosinante infiltrated the Donquixote Pirates under Fleet Admiral Sengoku's orders until he was killed by the crew's captain and his brother, Doflamingo, though it is unknown if there is a connection between them.
