things spring to mind...
denying a resource... making a resource unviable for the taking... a monkey might want a banana but won't walk through a sea of fire to get one
A surprising amount of high end military equipment would be useless, modern anti aircraft missiles are designed to hit modern jet aircraft, google
F-22 vs UFO for some idea about how that'd work.
Directed energy, kinetic energy and explosive weapons would be our best bet.
It really depends on what we are up against. Imagine a UFO designed to fly through a meteor belt, with defensive lasers to take down any incoming
projectiles... And shielding to withstand solar radiation... I really doubt a surface to air missile, or an unguided rocket would have any chance, and
a hail of artillery might just show up as a meteor shower...
I'd count assets as anything that makes their survival more difficult and ours easier.
There's an idea in the video game Mass Effect 3 that is a little bit like what you describe, the war room, google it.
The other problem is that, comparisons are only relevant to what you are comparing them to.
Ie imagine Alexander the Great having an ego trip with his phalanx's, having no idea what a modern infantry platoon could do to his army. Let alone an
infantry platoon with air support. Or an infantry platoon with chemical weapons and air support.
Everything is relative, it's a difficult thing to quantify.
For all we know, in such a case, our atmosphere could be a better defense than anything else we'd ever invent in time to deal with an invasion, HG
Wells style but more basic, should we include atmosphere in military strength against aliens?
Also, if they are really that advanced (re your initial description of alien life), what possible reason could there be for them wanting to conquer
They could hydrogen from the space clouds and fuse that into almost anything in all probability... If they wanted water they could harness ice
asteroids, if they wanted metal they could find a meteor belt... *shrug*
I think they'd be more likely to go oh sh*t, crazy ape aliens, those dudes are violent, best stay away, maybe they'll wipe themselves out.
Oh what, they want to govern us? No thanks! Those arrogant power trippers!
Anyways... Expect the patriot batteries to be unable to get a lock, same for the air to air missiles, all we've got left is GPS guided weapons (until
the satellites get taken down), and then we've got kinetic energy weapons, dumb bombs and laser guided weapons, and nukes designed to take out
cities/land installations, which are probably more effective against us than them... *shrug* We are not that mighty I reckon. For all that money we
spend, we don't spend it to fight aliens, we spend it to kill humans.

us as arrogant power trippers.
