Can you explain why simulating battle: 4 EMP troopers and 4 Rocket troopers defeated 2 AI tanks and 2 Razors with no losses, and in real battle I've lost all troops, and defender nothing?

does the opponent have extra xp on their units?

can you be more descriptive on the type of units... like was it a heavy unit with beam weapon with range upgrade....

I've put everything... It's all in battle simulator. I mean all the names are as in battle simulator. And I've checked the results several times... And I know nothing about xp, and dont understand what hp=1 means... Can I get this information from somewhere?

tappa when you use a spy you can choose to use it to make enemy troops down to 1 hp... thats what its for....

once again i really suggest you to get a mentor... all of this should be on the wiki

with each battle your units win the more experince they gain and the harder they are to kill you can keep an eye on your units by inspecting them to see how they are progressing
hope this has been of some help
