The foundation and heart of the Panzer Grenadier universe is, of course, the Panzer Grenadier series which began all the way back in 2000 with Panzer Grenadier.

In 2009 the core ruleset was modified and expanded to support World War I warfare and the Infantry Attacks series was born with the launch of Chihuahua Incident.

In 2013 the core ruleset was again revised to support more contemporary engagements and the Modern War series was born with the launch of Sword of Israel.
