Base 1 is one of the six battlefields you'll need to win in order to gain access to Koenigsdorf. This specific base employs the Sovani known as Snievan, the one from the quest After a Day's Work.... To get to him you have to defeat the foot soldiers first. The fight starts with three soldier unions, one Stormtroopers and two Commandos. There will be reinforcements after defeating some of them, a Cleric Squad, two Stormtroopers and two Commandos. Once you take them out a "mini boss" appears - a Tactics Squad together with two Stormtroopers. Two additional Magus Squads will appear the next turn in your back.
