In Just Cause 4, Squad Reserves are used to conquer new regions. Here’s how to unlock more Squad Reserves:
- By increasing your Chaos Level: To do this you must destroy red enemy objects in bases or destroy hostile vehicles. These can be, for example, gas tanks or power generators. Objects that earn you chaos are colored red and can be destroyed. Each Chaos Level gives you a couple of Squad Reserves. The progression bar to the next level is shown in the top right corner of the screen.
- By liberating a region that gives you additional squad reserves: This only happens when a hostile region is bordered by 2+ of your friendly regions. Then instead of costing squad reserves to attack, the region will actually earn you additional squad reserves!
The amount of Squad Reserves is only an issue in the early game when your Chaos Level is still low and there are lots of directions in which you can conquer new regions. It’s best to focus on the Windwalker storyline in the southern part of the map first. After that you should have a high enough Chaos level and enough squad reserves that it’s no longer a problem. Do the Thunderbarge storyline next (northern part of map) and the Sandstinger storyline last (western part of map).
Also, when conquering regions, go for the ones that cost the least squad reserves in the beginning (the ones that cost only 1 or 0 reserves). Then you can corner hostile regions until they give you +1 or +2 reserves.
