Sensha-dou (戦車道) is the fictional martial arts of Girls und Panzer.
Sensha-dou is a form of martial arts that involves the use of tanks as weapons. This martial art is exclusive for high school and college girls (with a professional league in development) in order to develop their self-esteem as young women, assist in becoming a professional and efficient citizen, and develop the characteristics necessary for motherhood. It involves two opposing school teams, each possesing their own set of tanks, combating in established league matches. There are two types of matches in Sensha-dou, the "wipe-out match" and the "capture the flag" match. The wipe-out match is when one team must eliminate all of its opposing team's tanks in order to win the match. This type of match will favour the team with superior tanks, for it is a battle of attrition. The capture the flag match is when one team must eliminate the opposing team's flag tank in order to win the match. This type of match will give a chance for an unfavourable team to win for they only need to eleminate the opposing team's flag tank, usually by use of superior strategies and tactics despite the odds against them. In Sensha-dou competitions, only 10 tanks per team are allowed for first round up to the quarterfinals, 15 tanks per team for the semi-final round and 20 tanks for the final round.
- The tanks which will be used must be designed or produced before August 15 1945, which is the end of World War Two.
- The ammunition used must be certified by the league to keep the participants safe.
- The armor used on the tanks must be certified by the league to keep the participants safe (No open top or rear).
- All tanks must have judging devices installed onboard. When the tank is hit, these devices posses a microchip which will determine if a tank is eliminated or not, depending on the angle and velocity of the impact (If eliminated, a white flag will appear on top of the tank or in some cases, if the eliminated tank was blown upside down, on other parts of the vehicle).
