Here are the top 10 military traditions that need a lot of explaining to your civilian family members.
Firing Inside the German PzH 2000
Only one crew member is visible, assistant gunner, who loads the propellant manually. Also in the vehicle are the driver, the rear machine gunner, the gunner and the commander. The automatic loading system handles most of the workload. The Panzerhaubitze 2000 ("Armoured howitzer 2000"), abbreviated PzH 2000, is a German 155 mm self-propelled howitzer developed by Krauss-Maffei Wegmann (KMW) and Rheinmetall for the German Army. The PzH 2000 is one of the most powerful conventional artillery systems currently deployed. It is particularly notable for a very high rate of fire; in burst mode it can fire three rounds in 9 seconds, ten rounds in 56 seconds, and can fire between 10 and 13 rounds per minute continuously, depending on barrel heating. The PzH 2000 has automatic support for Multiple Rounds Simultaneous Impact (MRSI) for up to 5 rounds. The replenishment of shells is automated. Two operators can load 60 shells and propelling charges in less than 12 minutes.
