Just wanted to sum up what is stated in the article so far, because I have read some speculation about things that are already relativly clear:
1. Both seem to have 2 wounds, because there are 2 wound tokens within the box. All expansion packs so far followed that pattern.
2. The Mortar seems to have suppressive (either that or the small part of the card that is shown reads "support" from the "Fire support ability" instead of "supressive"
3. Both the Mortar and the Mark II Medium Blaster have the Fire Support ability from the clone troopers. They can support any friendly unit, not only their Shore Trooper or Veteran Squad.
4. Both can be included as a heavy weapon upgrade for Shore troopers/Veterans. If you do, they have to be deployed as a seperate unit but do not seem to count as a seperate unit for army building purposes. They also block the heavy weapon squad, so the unit cannot take the T21B or CM-O/93 any more.
