# Patchjobfleet

The PatchJobFleet element describes a Fleet whose ApplicationInstances will be patched (in combination with other selectors).

This element is one of the [PatchJob](/game-hosting/elements/patchjob.md) properties that define the selection of ApplicationInstances to patch.

The other PatchJob properties that create the selection of ApplicationInstances are:

* DeploymentEnvironment ID (`PatchJob.deploymentEnvironmentId` property)
* Application ID (`PatchJob.applicationId` property)
* One or more old ApplicationBuild IDs (`PatchJob.applicationBuild` property)
