SIDRAT Vessel ('Green Box')

Alien transport craft resembling a TARDIS in interior scale, operated by the War Chief and used for temporal and spatial transportation. The vessel was initially used to trap the Doctor, Jamie, and Carstairs in its landing bay, but the Doctor gassed guards, reset controls, removed symbols, and rerouted it to evade pursuit. It later rematerialized in the resistance barn after the Doctor's monitor transmission, becoming an escape and strike vehicle for the resistance. The craft can materialize abruptly in resistance strongholds (e.g., the barn and Smythe's Room) and is capable of transporting reinforcements, leaders, and captives across space and time zones. It has been both a tool of enemy threat and a hijacked escape vehicle, playing a critical role in the resistance's efforts against the War Chief.

Carstairs destroys the SIDRAT

The SIDRAT is the primary target of the ambush, a vulnerable War Lord transport craft that materializes in Smythe's Room during its activation phase. The resistance's plan hinges on destroying it before it can disgorge more guards or transport supplies, but the War Lords' forces counterattack first, killing the gunners. Carstairs seizes the moment by tossing a grenade through the SIDRAT's open door, triggering a catastrophic explosion that obliterates the craft. The SIDRAT's destruction is a pivotal moment—it neutralizes an immediate threat, deals a blow to the War Lords' logistics, and demonstrates the resistance's ability to adapt and strike back. The craft's smoldering wreckage dematerializing in smoke serves as a visceral reminder of the stakes: every victory is hard-won and temporary.

Before: The SIDRAT materializes in Smythe's Room with its door irising open, vulnerable during activation. It is implied to be carrying War Lord guards or supplies, making it a high-value target for sabotage. The craft is fully operational but exposed, its door providing a critical weak point for Carstairs' grenade.
After: The SIDRAT is completely destroyed in the explosion, its wreckage dematerializing along with the smoke. The craft no longer exists as a functional threat, but its destruction comes at the cost of the resistance gunners' lives. The absence of the SIDRAT post-explosion leaves a temporary void in the War Lords' operations, buying the resistance time—but also ensuring retaliation.
