1.tanks are units that have high health, high defense and high physical resistance, for example knights, paladins and guard droids are tanks

2.units are categorized by races like in the link I gave you(you can see droids there under dwarves) and lots of equipment adds bonuses to specific races so one race army is preferable for greater synergy

3.in the battle, by holding shift and clicking on any unit you can see all info about that unit, what type of attack it has, speed, resistance, initiative(very important because units with highest initiative will act first in a round).

For example spiders and snakes have poison damage so guard droids and repair droids, which have 80% resistance to poison, will receive very little damage.

Basically, you just have to read the unit infos, everything is logical.
