Eliophotes: building 12b1 - "67B", "68B", "32MK", "ALI S."/"AUS", "ΛΟΚ [LOK]".

[Updated on the 17th of June 2009.]

And while DT's there, he's giving me a comprehensive education:

67B means the seira that those soldiers were from.... [B is the summer draft; A is the winter draft.]

67B means that the inscriptions were made between 1985 and 1987 by the 67B group since thats when they would have been drafted.

As Get Real! notes,

If you add 18 years to that you get the draft year.... [So, "67B" would be "ESSO 85".]

But soldiers always graffiti the first.
