It pretty much has to be the main power gen', seeing that Veers specifically announces he's blowing the main power generator up when he takes it out.

Whereas in R.O.T.J., the radar domes are destroyed because the Rebels are finally penetrating the Executor's shields, but the unfortunate sequence of events gives the impression the domes are shield generators.

Oh, the joy of SW nerds coming together to debate the finer details of the movies. Goody [/self-ironic smartass mode].

Someone didn't watch the Special Edition. The generator is clearly labeled with huge banners and flags bearing the words "MAIN POWER GENERATOR F.F.S.!!!111" in an attempt to end all debate .

Play the Rogue Squadron series and you see that even more often. If it doesn't move and can be blown up, it's a shield generator;).

11-year old playing RS III: YAY! I blew up teh sheild generator!1111 G00dy 4 me-e-e-e!!111
Me: "Er, that contraption is called a 'Death Star'.
11-year old: "STFU Teh game r teh appr0ved by L_cas!

[not trying to make fun of anyone here, just the RS series itself]

Hehe , I think when it comes to naming stuff and being accurate we will look to the movie.

In ROTJ , Han blew up the power generators (those orange things inside the bunker complex) which caused a chain reaction all the way up to the Shield Projector , miles to the north. So whether you call them power generators or shield generators it doesnt really matter since they are the same thing. The actual orange things are power generators ..but that power is used to generate a shield..

*nods*  I guess in conclusion it will probably come down to the mapper and the objectives he's decided upon for the map   from there it's just going to fall in with "what works best on the map"

Shield generator explodes, sheild goes down....

Power generator explodes, shield goes down....

Thing no one really knows the name of explodes, shield goes down....

It seems that in the movies, no matter what you destroy it's going to be a shield generator tongue

Incorrect. No matter what you place a small amount of explosives on, something much bigger explodes.

Same with this here.  They blew up a target then the next message was "their shields are down, you may commence your landing."  Whether you want to argue the semantics of if it's a power generator or a shield generator, what everyone will believe is "if you shoot the funny round thing, the shield generator is dead."  As such I don't actually think it matters whether we call it a shield generator or a power generator, however my inclination is to call it a shield generator because that's what everyone associates it with.  And even if they are power generators, again, in RotJ Han destroyed the power generator for the Endor shield yet we still saw the shield generator explode.  It seems that in the movies, no matter what you destroy it's going to be a shield generator

Interestingly Star Wars: Force Commander (one of my all-time favorite RTS games) had them as shield generators.  You could put them down and everything inside their "shield bubble" would gain shield ability.  As such even lucasarts has made this discretion/mistake before

I loved that game.  It was so great.  Multiplayer was also the best.  Except for when my kid brother discovered that you could rename troops to whatever you liked.  He would constantly rename single infantry men "Woodrow" and marched them up into the firing line to be "executed" to demonstrate what was going to happen to me

What Veers destroys is the power supply to the shields, much faster than simply destroying the shields themselves. This then allows the Imps to begin landing troops and bombard the base from orbit.

What we see Veers destroy is the Main Power Generator, which in addition to supplying power to the base is also providing power to the Shield Generator, which we do not see but probably looks like that dish on Endor in Episode VI.

Actually the shield system on Hoth would have been a little different to that on Endor, after all that shield was being projected far out into space to encompass a facility the size of a small moon requiring the massive shield projector array used by the Empire there.

By comparison the shield system on Hoth was a localised shielded area which would have required a number of shield generator modules dotted across the frozen wasteland that made up the territory surrounding the Rebel Base. These would have been considerably smaller and probably camouflaged to make them harder to detect, their design would be akin to shield generator blisters on capital ships.

After several viewings of the battle on DVD, it has become clear that the Power Generator and Shield Generator are different, but related.

What we see Veers destroy is the Main Power Generator, which in addition to supplying power to the base is also providing power to the Shield Generator, which we do not see but probably looks like that dish on Endor in Episode VI.

Therefore, by destroying the Power Generator for the shields, Lord Vader can land the 501st and orbital bombardment can also take place.

Of course, the reason the Rebels were able to get the shield up was because Ozzel came out of light speed too close to the system.

The Imperial assault was primarily aimed at destroying the Rebel's main power generators. This would shut down the theater shield protecting the base from orbital bombardment. General Veers led the assault personally, commanding an AT-AT walker, and crushed the Rebel defenses.

The cross-section of Echo Base seen in Inside the Worlds of Star Wars Trilogy shows 15 T-47 airspeeders, 9 in Hangar 7 and the rest in the transports hangar. Whether or not all of these participated in the battle is not known.
