I wrote about this but I was thinking about making this proposal visible to everyone as proposal issue.
I think that resources dont play major role currently and its quite simple what you need to do about them (just send one squad to guard it and thats it). I think it can be implemented in a different way and it would maybe be more interesting. If you could make a bar for each faction that shows how many resources that faction have it would have bigger impact on a game. For example every resource point should have a timer (like base) and when it counts to zero resource is either ready for gather (send a squad to collect it) or it simply increases faction resources by x amount. Faction resource bar should be split in few segments. For example max amount of resources is 9. If faction has only 3 resources it spawns squads with worst equipment, 3-6 and it spawns medium tech squads, 6-9 and it spawns hi tech squads. If faction have many people then it spends resources faster. For example 10 people = 1 resource daily. This could open a way for faction trade in the future if you plan to implement it. Important thing is resource timers should be adjustable in options menu and visible when you mouse over resource point. Also speed od resource decrease should be adjustable. There it goes... another idea :D
