The E-Web heavy repeating blaster was one of the most powerful repeating blasters in the Imperial arsenal. It could be broken down into into smaller pieces which made it very portable, but it could also take a long time to set up and needed at least two crew members to use it effectively.
The Thermal detonator was a grenade that was meant to be thrown or placed in a specific location. The grenade would then stick to any metal object nearby until it exploded.
