The lessons learned were incorporated into the new tactical concept named "neuer Schützenpanzer" ("new IFV") in 1998. Planning for the Puma as the successor of the Marder began in 2002. That same year, the German Army ("Heer") placed an order for the delivery of five pre-production vehicles and their logistics and training services at the end of 2004. On 8 November 2007, a budget of €3 billion to acquire 405 Pumas (excluding the five Pumas that had already been delivered to the German Army for trials) was agreed upon.
