Energy field

From Command and Conquer Wiki

An energy field, or energy shield, is a defensive barrier of energy used to protect whatever is contained within it.

The first known energy shield was projected from the Iron Curtain device developed by the USSR during the Great World War II. It proved to be impenetrable to all weapons of that age, and it is theorized that it may not be able to be penetrable at all (although the field could only be maintained for a short time).

The next major energy field was the Firestorm barrier employed by GDI during the Second Tiberium War. It was indented to protect entire bases instead of individual units or buildings. Like the Iron Curtain, it could only be maintained for a short time.

With the arrival of the Scrin, several more energy shields have been discovered. Unlike the Iron Curtain or Firestorm barrier, the alien shields can be destroyed if enough force is employed against them. They can be maintained indefinitely unless destroyed, though. The forcefield generator upgrade applies to the following Scrin: Annihilator Tripods, Reaper Tripods, Planetary Assault Carriers, and Devastator Warships. This non-regenerative shield is able to absorb damage and a single EMP blast, effectively doubling the resilience of the unit.

Reaper-17 also employs the attenuated forcefield upgrade to Shard Walkers, Seekers and the Tiberium mutated Reaper Tripod. Reaper-17 also has Shielded Harvesters, which is the only Scrin unit that natively has energy shields. This has lead some researchers to believe that energy shields may be new even to the Scrin.

However, the Scrin sub faction called Traveler-59 doesn't use energy fields, since apparently the power requirements would slow them down.

GDI had some Energy Barriers one to defend the Tacitus with.
