Answer:
-not what the question asks.
most of the items you need are available in the item store. you just need to loot jet pilot and TNT in certain job tiers. the most difficult part of it is you need to earn a lot of Cuban pesos to buy items cos they are really expensive just like you need to buy 30 wise guys which is 30000 Cuban pesos each. the other difficult part is you need to have a lot of Politico Corruptos which is you need to open a business in Cuba and you can only have at most 26 Politicos a day and you need almost 500 of it to complete the Cuba job tiers.
