The primary trainer for TIE pilots, and especially for TIE Bomber training, the TIE/ts is simply a TIE Bomber with an extended control pod to accompany a back-seat instructor. Being a trainer, the TIE/ts carries a slightly smaller weapons payload than the TIE Bomber, as well as other safety features. Old TIE Bombers are often remodeled to serve as TIE trainers.
