Riflemen Zooka Medic
This is a less common but still very effective troop combination strategy in Boom Beach. Riflemen, Zookas and Medics combine to overwhelm single-target defenses like the Sniper Tower, Boom Cannon and Cannon. Although Riflemen and Zookas both have low health, the Riflemen act as a fast-moving shield for the Zookas, and the Medics stay close to heal as much as possible. To make this tactic work, you need to make sure you destroy any Rocket Launchers with your Gunboat artillery and barrages before you storm the beach.
