and that shield projectors are versatile like "switch all power to front deflector screens" and "angle the shield while i charge up the main guns"
the rebels would have aimed the shields at the fleet and maybe overlapped them to present the strongest defense to bombardment
this would leave them vulneruble at ground level - they knew this hence they were ready for a land based assault
but they only needed time to evacuate
that ends the debate for me, i shall now attempt to get life
