Unarmed units not engaged
Unarmed units will not be engaged by AI units (sub or ship) on Plotted mission. This is due to the fact that the targets pose no 'threat' to the AI unit thus elicits no response. Once weapons are added to the targets, they are immediately attacked.

2. Unarmed merchants will sail right past without being engaged. This behaviour can be replicated with submarines, too. [ANW] Unarmed units not engaged (3.8.0).SCN
3. If the game is saved and examined in the SE, the naval units do see the enemy as Hostile and in range (if fired manually), yet they will not fire.
