I never take the Tactics skill! It’s better to take any other skill; even Diplomacy is more useful! If a faction’s units have low speed, the opponent will still go first. And even if the speed is high, I just don’t understand the point of the skill. Explain it to me.

1. You attack an opponent with fast units. You have the option to protect your ranged units before the battle begins.

2. You need to have your hero with a weak army escape from shooting neutral creatures – in the deployment mode, there is an option to “flee.” As a result, the hero remains alive; otherwise, he would have died and would no longer be available.

3. When playing against the AI, you can bring a “bait” unit forward, which the AI will attack first. As a result, the battle tactics can be varied, and you can take the lead even with slow units.

4. You can neutralize the opponent’s Tactics skill with your own Tactics skill – sometimes this is very useful if the opponent doesn’t realize your capabilities and expects an advantage that they won’t get in the end...

This is just off the top of my head...
I think there are many other ways to use Tactics.
