The Blaster I use is ROTJ BLASTECH E-11 blaster rifle. This type of blaster was used in the film and is used by 99% of all Troopers within the 501st This Blaster is only a side arm for a Sandtrooper.

Two of the main weapons carried by the Sandtrooper are the BLASTECH DLT-19 Heavy Blaster and the BLASTECH T-21 Light Repeating Blaster.

If you look carefully at the sandtrooper's you will see that the trooper on the left is carrying a DLT-19 and the trooper at the front is carrying a T-21.

This is a good one of me carrying my T-21.  And my E-11.
