The biggest factor in how long this takes is determined by the player. Many people send waves in to take out camps as soon as they can win the battle. This is a self defeating approach, you need to try and take out early camps with one crushing wave that defeats the enemy in one round of combat. Any more than 1 round and you are throwing away recruits- and then it takes longer- and longer the next time etc...until it just seems like it is taking forever. Be disciplined and do not throw away recruits like i'm guessing 70% of people do early on cause they just can not be patient. This game punishes those with little patience severely.
