The more I have played the demo the more apparent it has become that their is a lack of ground units to command. The unit classes in the game represent only a fraction of the unit classes in the Star Wars universe and I think their is definitely room for the following 3 classes. Furthermore, I feel that the slow pace of the ground troops causes the game to loose some of its Star Wars feel. Star Wars draws its combat style from several human conflicts(WW2, 17-18th century naval warfare) and I feel these unit classes are essential to keep that style. Repeater Troopers-This guy is your machine gun emplacement, he doesn't move around that much, is hard to setup but is great for defence and for attacking concentrated groups of troops. The machine gun was one of the key inventions that defined combat since the U.S. Civil War. This is the e-web and medium repeating blasters from Hoth. Troop Transport Speeders- These carry your troops to the battle, they get them their quicker then walking and hold them safe inside until your tanks have eliminated the heaver units. Helps define the pace of action. We have seen these numerous times in the Star Wars universe, aka MTT's/AT-OT's. "Strike Mechs"- This is your AT-PT, AT-RT, or Gien and Flash Speeders this unit is lighter then a tank but faster, designed to support your infantry where the tanks can't go.
