If I place markerlights on a unit that is inside their dedicated transport and subsequently destroy said transport, can I still use the remaining markerlights when I target the disembarked passengers with another unit in the same shooting phase?
Do markerlights put on a unit embarked in a dedicated transport remain on the passengers after the vehicle is destroyed?
No. The markerlights are on the transport, not the unit inside. Remember they are separate units, and generally you can not target units inside a transport (template vs. open topped being the exception). Any markerlights on a destroyed unit are removed with the unit.
The only way that would be possible, is if the targeted unit had a way to embark during your shooting phase. To my knowledge that's not possible.
Note: In 8th edition, this is still true, except that there are no templates anymore.
asslum's correct - you cannot target the unit inside the transport. That said, there's nothing stopping you from targeting the unit with more markerlight's once the transport is destroyed...– user16341Oct 24, 2016 at 23:01
I see. I thought that the troops and the dedicated transport formed a unit, hence my misunderstanding.– KenjiOct 25, 2016 at 11:32
@Kenji - they do for selection and deployment purposes, but not for targeting– user16341Oct 26, 2016 at 5:33
