Automated Unit Missions
A group of units could, depending on what units are in the group, be sent on an automated mission. This would make micromanagement a lot easier, freeing you up to stress about your colony.
IE
If you got together a group of say, 5 spiders, 3 EMP lynx, and 3 RPG lynx, then you could tell them "Capture & secure" then click on an area, and they would move to that area, destroying all combat units and capturing all noncombat units they pass by.
If you got together a group of 4 Microwave Lynx and some Convecs with Guard Posts, you could tell them "Take & hold area" and they would move in, destroy enemies, and build guard posts to defend the area.
A list of mission ideas:
Capture&Secure (available to groups with Spiders, EMP and combat units
Take&Hold Area (available to groups with combat units and/or ConVecs carrying Guard Posts)
Destroy Light, capture Heavy (attack enemy light tanks, capture their Tigers, available to groups with Spiders, EMP and combat units)
Lay Siege Framework (Build a small siege camp, available to groups with combat units and ConVecs with Command Center and Vehicle Factory and some Guard Posts)
Destroy Base (Go to enemy CC, destroying Guard Posts as you go along, avalable to groups with combat units)
Intercept (Cut off enemy units and attack them, available to groups with Lynx)
Flank (Split up and attack enemies from both sides, available to groups with Combat Units)
Repair Area (Repair all damaged structures in the area, available to groups with Spiders, Convecs or Repair Vehicles)
