Super newbie help

For units (troops, fighters) you need to research construction and then the specific unit type. You also need to research smaller and troop weapons. Then select unit under design. You should beable to upgrade all facilities by selecting the upgrade button on the construction que screen.
Note it will take about 1 turn for every 2 facilities you upgrade and will not be done until all of that type are finished.
