Arms Dealer where you can buy equipment off the black market once a sea port is 'liberated' which will allow hte player to buy higher graded military equipment for antistasi currency,
random events like aircraft crashes and hte player can salvage the wreckage before a rescue team arrives,
occupants logi incidents where the players can salvage wreckage's,
maybe a task that involves naval assets a bit more? maybe like boarding a vessle and comandeering it or again salvaging loot crates off in bodies' of water,
receiving air drops,
a feature that lets the player order stuff to be made in factories would be nice aswell - like guns and/or vehicles
i think things like the above would keep game play more varied and different.
You devs have made an amazing mod/project and i hope to see it developed even further in hte future arma games, well done and thank you from myself and my community
