Grenadier

The Grenadier is a unit under the Light Infantry category that can be trained through the Barracks once the player has reached the appropriate level.

Overview
The Grenadier is a useful infantry unit, able to attack from the second row on the battlefield, even if it was blocked by an enemy in front of it. They have a relatively minor flaw, however; their ammunition is limited to three grenades. The grenades are useful for dealing with wild creatures (Raptors and Boars), as they can take a large chunk of damage off in one hit. Grenadiers are also useful for destroying watchtowers and tanks, although there is a very high chance they can be destroyed in the process. In early levels from when Riot Troopers appear until Mini Tanks become available, these are the best unit for kill those pesky Riot Troopers.

With the version 1.3 Update, you'll be able to issue Flashbangs to your Grenadiers with proper research. Flashbangs will not do damage but will supress units easier.

Description
Grenadiers like explosions, and explosions remind them of their war history. These units hold 38mm Frag Grenades that explodes on contact with any solid, hard surface. The grenades are suitable for destroying Pillboxes and Watchtowers faster than bullets can, and can be really effective against any type of Artillery. Grenadiers play an important role of defeating their enemies behind other enemies.
