Grenadier Training is a technology that can be researched at the War Center in Tech Level 3. It costs 150 Food and 150 Nova, and increases the attack speed of Grenade Troopers by 10%.

This technology is excellent if the player uses a lot of Grenade Troopers, particularly when combined with Explosive Yields Increased. Players that only use Grenade Troopers sparingly, or not at all, can safely ignore it.

"At Tech Level 3, you may develop new techniques that enhance your Grenade Troopers, allowing them to attack twice as quickly as before."
