Bible References on Gun Sights

I've been following this one in the news.....here and in NZ.  Wow, this just strikes me as plain weird.  Weird in a way that only the US can be weird....and exactly how long have they been doing it? Trijicon, the manufacturing company originally issued a statement saying "As long as we have men and women in danger, we will continue to do everything we can to provide them with both state-of-the-art technology and the never-ending support and prayers of a grateful nation.".... then backed down the following day saying  they would remove the references given concerns raised blah blah blah....well actually given their single largest customer (US Department of Defense) probably said, stop it or no more contracts from us!
My bet is that every military inventory system around the world who has these sights not only has the serial numbers included but also has the biblical reference as well - when do you suppose somebody noticed?
