Anyone else notice?

They have SNAPTA on their uniforms, but one of the last cutscenes shows Artyom revealing dog tags that say CNAPTA on them. Is this a typo in the game? Anyone know what SNAPTA means and if CNAPTA is a word that's supposed to be in the game?

@Frag_Maniac: Its SPARTA. The insignia on some of the uniforms uses a lightning S, similar to the nazi S, used on SS uniforms.
