You can also use XP Boosts that will also help you increase your level much faster. You can buy them in the store with the game currency.
Something interesting is that Rockstar Energy Drink and Chips Ahoy Cookies have a promotion in which they grant codes to get free supply drops. For this you will have to buy the special promotional packaged products and follow the instructions on the packaging to enter the code to claim the reward.
Now that you know how to get supply drops quickly in Gears 5 we hope you can keep moving forward in the game quickly the same.
