Roller Sentries are Grineer Roller-like drones that can deploy into sentry guns when not moving. They are deployed to support Kela De Thaym during the Assassination mission against her. They were added in Update 18.10 and originally appeared in the Operation: Rathuum.
- Though weak, they can be Mind Controlled for the full duration, unlike the Executioners themselves who suffer reduced initial duration and even less duration on re-casting.
- A variant of this enemy can be summoned by Executioner Reth and the Aerial Commander under the name "Reth Roller".
- Reth Roller was commonly seen in the Wolf of Saturn Six Assassination.
