Japanese Strategic Self Defense Force
The Japanese Strategic Self Defense Force (JSSDF) is a military organization, the main branch of the Japanese military under the direct command of the Japanese Ministry of Defense. It has a background role in the Evangelion TV series, serving in a military support capacity for Nerv. The JSSDF serves as a primary antagonist in ''End of Evangelion''.
The JSSDF was formed in 2003 in response to the outbreak of war between China and Vietnam over the Nansha Islands as a result of post-Second Impact tensions. As a result of this new political climate, Article 9 of the Japanese constitution (which forbid Japan from maintaining an offensive military force after World War II) was apparently abolished.
The JSSDF functions in coordination with United Nations forces in providing support for Nerv and the Evangelions when they attempt to repel Angel attacks.
The JSSDF arsenal includes N² Mines.
However, in The End of Evangelion, Seele (through the UN) orders the JSSDF to invade Tokyo-3 in a massive leave-no-survivors assault. The JSSDF easily turns on its former allies, mercilessly advancing through Nerv HQ and unconditionally terminating any personnel they encounter.
