Just one question, why did they never bother to stop and pick up the laser weapons from all the dead soldiers?
shareThere was an attempt to explain this in the 'Death Tide' novel - the resistance didn't have access to the power sources for the Visitor weapons, so they only lasted so long before they became useless.
sharewell the real life reason is that the laser effects were quite expensive to create so they limited their use on screen.
on a similar note, with all the shuttles donovan's stolen you'd think they would have kept a few for the resitance. sure a few crash landed but there's a number of them they got away scotfree with never to be seen again. lol
