hy all,new to this forum,got here accidentaly and i liked the topic ^.^
considering the numbers u gave them,we would win...100%.
1)a)Vader: considering he's the only guy in black armor running around armed with a shiny stick ,cutting ppl and throwing them around by moving his hand.also beging the one who gives the orders i'd say we would totally notice he's the leader fast.
k now we know his the best,he's the leader.Vader is powerfull,but he cant affect vehicles with his power...master Yoda barely lifted a small ship from the water ,how much batter could Vader be,if he even is better >.>.Vader cant just blow tanks and jets just by looking at them(he would've done it in the space ships battle with Luke when they blew the Death Star,nor he's fast enough to stop a bullet.at the speed a bullet moves,he wont even have time to raise his hand and use the force or move the lightsaber.i know he aint that fast because the lightsaber battles are rather slow.they move just like normal ppl.i could proly chalange him to a lightsaber only battle myself and even beat him is he didnt use the force and i'm not some kind of shaolin master.so if Vader isnt in-humanly fast,a sniper, shooting a super-sonic 50 cal bullet from 1 km right in his head...even if his armor wouldnt be pierced(considering its made from sth very stong),his neck would snap like a straw if not even his head would be ripped off(it can pass through a block of concrete,it can surely break a neck).also considering that by some miracle he survives,a tank shell is impossible to see with human eyes when its launched so Vader wouldnt be able to stop 3 sniper and 3 tanks shooting at him in the heat of battle(i just randomly chose 3,it could very well be a 50 ppl squad of snipers)...per total...Vader would be pwned fast. PS:a sniper can shoot a static target from 2 km.it can shoot Vader moving easly from 500m-1km,and thats waaay safe from the battle so they wouldnt be distracted.
1)b) considering they had a shield and Vader couldnt be sniped,we'd just bomb the land in frond and retreat,and when the vehicle that makes the shield is positioned corectly bang ...and its out,then see reference 1)a)
2)with Vader out of the way,there would be nobody left to control the army.they'd go into chaos and lose...but lets consider someone else takes control of the army.with Vader out of the way,a nuke can vaporize anything and everything on a diameter of 10 miles.and i mean vaporize,poof.the huge pressure,thermal radiation ,EMP that comes with the nuke would reduce their entire army to absolute 0.their machines wouldnt survive the EMP.the imense heat would just boile everybody in their armors and vehicles...it would be a massacre.also i'm sure that in such a case,the US wouldnt hesitate a moment to blow a nuke even in the center of NY to stop an alien invasion.they'd even be happy to do it cause they would test their bombs properly.
and such the imperial army would be taken out by a couple of snipers and a nuke.
they couldnt know where all the nuclear armament of the world is hidden,come oon,only god knows that.
if they could actually jam our radars and comunication...thus match their technology with ours(we dont know if they use electro-magnetic beams to comunicate in Star Wars),then we would most likely be able to do the same,even listen to their radios or defend from their jamming devices.considering they had some tech and could jam our beams but we couldnt mess with theirs,they couldnt just jam the entire planet...lets say they could,the Japanese would send kamikaze in the middle of the fight and blow the nukes manually(they had kamikaze in WW2).the snipers wouldnt need radios to shoot.
to sum up,with vader out of the way the army with the numbers u mentioned wouldnt have a change against us.0% chances.their walking vehicles cant pass tranches(the smaller ones they used in the woods(donno which AT is which)),they can be taken out by rocket lauchers,mines,attached bombs.the bigger ones can be taken out by just tieing their "legs"...there are plenty of ways to do it without the speeders:helicopters,romote control planes(the special ones the army has,not toy ones),they could even improvise one by tieing 2 rockets and shooting them each on one side of the AT.if the rockets dont colide,they will go around the AT super fast and do their job magnificently(this can be done by 2 smart soldiers with 2 rocket launchers and a string tied to the head of the rockets,they only need to get 2 legs,not all 4).the AT are stupidly created by George Lucas.they would totally fail in combat...totally.hell just shoot tank sheels in a big AT while the leg on the opposite side is in the air and the force(the real one) will bring it down.or u can tie a string around a leg of one big AT and the other side of the string around another AT and they will bring each other down.
about the 500k army...considering our bullets wont pass their armor(rocks did their job fine,but wtf lets make this harder for earth),just send an all out army of armored vehicles at them .
all of what i said is done on leveled ground so they would have an advantage.in cities,mountains,hills,the big AT would be shit and we'd have the overall advantage.
there is no way an army with the parameters u gave could beat Earth even with this shit tech we have...
