For the moment, finishing a mission allows only gain of resources. So, there is no big difference between mission and convoy (except the fuel). I Think that finishing a mission could allow access to special components, weapons or shields (picked up technology). This would give more consistency for the scenarii of the missions.:rolleyes:
Or find directly weapons on the ground, left by dead mechs or dead base, that we could have in the weapon dock. Going on them to take them.
We could also find artifacts, weapons or resources hidden in the map to explore it after the defeat of ARMA.
