Just like in the main menu, you can also view your unit statistics in-game. You can also expand the individual 4 tabs (attack, defense, life, movement). And not only for you, but also for an enemy or friendly unit if you click on it (then top left). For cavalry, in addition to speed, it is primarily the charge impact that determines who will deal out the damage in a direct 1vs1 confrontation. However, this charge impact can be improved through gear and consumables, so you can't necessarily always know who will win. Looking at the stats (if you have the time) will make or break a fight.

In addition, you should generally learn quickly which unit type is good, medium or inferior to which unit type.

You can see this in Unit Comparison.

Next to this you can go with your mouse cursor on the enemy units, where you get a threat assessment.

Low Threat (green) = You are stronger

Medium Threat (yellow) = Can't say for sure

High Threat (orange) = You are outclassed

Very High Threat (dark red) = You will die!
