Why are the aliens attacking earth?
...falls ancient flying object, aliens need ancient technology, humanity has refused to return the aircraft, so there was a conflict.
I want to share my idea; Propose to add in the X2 disposable rocket launcher M72 LAW
Weight: 2 kg
Time Units (TU) per shot:
-Snap=16
-Normal=20
Pros:
-low TU cost
-low weight
Compared to rocket launcher
Weight: 6 kg
Time Units (TU) per shot:
-Snap=27
-Normal=36
Pros:
-multiple types of ammunition
Cons: -big TU cost
-big weight
