What if you run out of troops in the game of risk?

If you run out of troops in the game of Risk, you can no longer participate in battles or defend your territories effectively. This typically means you're at a severe disadvantage, making you vulnerable to being eliminated by other players. If you do get eliminated, you may be out of the game entirely, depending on the rules being used. It's crucial to manage your reinforcements and territories wisely to avoid this situation.
