Bombers and lasers are unaffected by any bonuses. All bombers, regardless of who controls them and what bonuses they have, have a 10% chance to destroy a laser. All lasers, regardless of who controls them, will destroy 10 air units, starting with transports and then moving to bombers.
As far as I know, race attack bonus, military science bonus, no fear bonus, and fleet admiral tag bonus all stack multiplicatively. I assume it is not additive because income bonuses stack multiplicatively. This means that if you are a wardancer with no fear and 10% military science you will have +80%x1.1x1.1=+97% bonus when attacking someone with a net zero attack/defense bonus.
But man is not made for defeat. A man can be destroyed but not defeated
