DoD would need to cleanse tons of current usage and past history to eliminate the number 69 and Phallic Symbols from the books. IMHO, 69% or more of the ordnance items we store, load, fly, drop everyday "in my perverted/simple mind" look like a penis and function like a penis. The US military (this goes for the rest of the world also) commonly utilizes #69 to ID these penis shaped ordnance items including; bombs, projectiles, rockets, nukes, etc. There are also a few other #69 designated items (components/equipment/etc) the US military has developed that are suitable for use in the traditional #69 sexual mode of operation like "the M-69 Vietnam era flak jacket with a M-69 gas mask (PRC gets credit for this item)". Here's just a few examples of ordnance/other stuff identified by #69 and there's tons more:<)
GBU-69/B Small Glide Munition; The newest GBU in the USAF arsenal.
M-69 Mortar
W-69 Nuke Warhead which was the physics package contained in the AGM-69 SRAM (retired in 1993). The AGM-69 SRAM was carried by the B-52. If the USAF was still using the AGM-69 with W-69 Nuke Warhead - they'd be used as one of the primary nuke ordnance loads for the B-52's of the 69th Bomb Squadron. The PC crowd would have a fit with this type of Triple 69 (69/69/69) sexual/nuke/Phallic Symbolism. Today, I have no doubt, that this Triple 69 formation would be the first item on the chopping block at the upcoming New START negotiations.
M-69 Incendiary Bomblet "Which Spewed Burning Gelatinized Gasoline That Stuck to its Targets"; General Lemay would be canned today for employing this Phallic Shaped/designated #69 weapon with such sexually explicit effects.
I'll close with this tune that will eventually be banned from all US military installations due to its sexual genesis (although it would make a good theme song for units designated with #69); ""Summer of '69" and its lyrical meaning. Adams said the song was about sex and making love in the summertime. "69" is a reference to the sexual position, 69".
