So you will have to make adjustments while invading and then remember to set it back to the Home setting. You also don't want to be taming animals at this moment. Both tasks are completely unnecessary, as fire can help you just as like when raiders set your base on fire and cleanliness is unimportant. This can prove detrimental if your settings have for example Firefighting with priority one and same for Cleaning. The first problem is that your caravan will follow the Work tab you use at your base (ideally, we could have more work tabs). If planned carefully, you can take down the most dangerous ones first, leaving lesser ones to clean up later. One common concern may be counting their numbers, but always remember that once around half of them are defeated, the remaining survivors will flee. This gives you time to set up minimal defensive positions, but not enough to build a whole base (which is pointless because the map is temporary). Enemies will remain roaming around their base initially and then come at you. Attacking enemies does not mean you have to fight right away. Upon entering enemy territory, your soldiers will remain drafted and ready to fight.
