Activating while engaged

[Grey Knight]

I've got a question about activation while in base to base with an enemy.

Let's say my Model is in base to base contact with an enemy when I activate it. My options now are:

1 – engage the enemy model in melee combat
2 – concentration / focalization / shoot action
3 – run away

Ok, question 1: Do I have to take one of these actions? Or can I just activate, do nothing and end the activation.

Question 2: What if my model has been immobilized? I cannot perform any of the above actions now. Do I automatically end the activation? Do I initiate a melee combat against the enemy and roll no dice?

shoot action

You can't choose a shoot action if you start your activation engaged.

You must do something...no pity for sleepy miniatures . But a mini cannot shoot if it is engaged.

Question 2: What if my model has been immobilized? I cannot perform any of the above actions now. Do I automatically end the activation? Do I initiate a melee combat against the enemy and roll no dice?

Each time an immobilized miniatures is activated, if it is in an opponent melee zone, one ennemy minature ( to your adversary choice) attacks it, and you cannot reply. Consider it as a punching ball fr the duration of its Immobilization state.

That helped, thank you.
