please explain I dont know what you mean by a button.

a button you know, like in a war mill there are buttons you click on for weapon and armor upgrades

Well, have a look at the War Mill.

You might notice it has a couple upgrades in "Techtree - Researches available".

Units that get something from those upgrades have them in "Techtree - Upgrades used".
