Since the game's events take place on an island, for each task the team will need to find a way to get to the place where the task is happening. You should choose a ship based on what the player has and analyzing which ship will be more efficient. The maximum number of ships is 2. Each ship requires money for maintenance per hour.
For example, for a task in which the player will need to sail through scary waters (where there are many hostile units), it is advisable to give a large military ship. If the journey by water will be safe enough, but on a large land the soldiers will need a lot of equipment, then it is better to give a cargo ship, which can accommodate a lot of everything.
The player chooses the number and quality of soldiers, based on the soldiers who work for him. Each soldier has a cost that he gets per hour (the cost depends on his skills).
