Understanding Defensive Fire

[Strela]

The manual says:
"Unlimited op fire (as in Squad Battles)."

Exactly. There is no limit to how many shots a unit may take during an enemy's turn.

But still a limit that a defending unit can only fire 3 times at the same attacking unit ?

There is a limit of three fires in the phasing players turn. There is unlimited fire during the AI controlled defensive fire phase.

One of the reason there is unlimited defensive fire is to prevent players from using an expendable unit to absorb the three shots of defensive fire and then bring forward other units with impunity.
