The
T-91 Executioner has left
HCS service after the last 20 were withdrawn from the training unit they were serving with. The tanks are now all in
HCS Reserve but are unlikely to be reactivated. The T-91 was the ultimate development of the HCS MBT, marrying the hull of the T-89 with a new unmanned turret. However by the time the T-91 had arrived the
Clone Wars were over and tanks were no longer needed to combat their DDS equivalents.
The HCS decided to standardise on the T-89 and T-55Z and over time have begun rationalising other types. The T-88 is no longer in front-line service though several thousand remain in HCS Reserve (in readiness units unlike the T-91).
