Just looking for clarification about this ruling.

If I am attacking an objective with mulitply unit, does the unoppsed bonus apply to each unit that strikes or do I only get it once? In this situation twice.

you only get one unopposed bonus damage per engagement, not one per unit

Simply stated, if the attacker has units that survived an engagement and the defender either did not engage in defense or had no units that survived the engagement than an additional "unopposed" bonus of one damage is awarded.

This can happen only once per engagement. If you engage multiple times in a turn, it is possible to get an unopposed bonus in each.

Awesome. Was playing with a friend that other night and we were playing one unopposed per unit. Thanks for the clartification.
