A major problem is that language requirements change.
Prior to 9/11, I do not think we even taught Pashto or Dari. Probably not a lot of Chinese, either.
Lots of Russian and Eastern European language training though. The first teams into Northern Afghanistan did not speak the language and finally had to speak Russian (which they were not trained for, but a couple of guys had been in Russian slots before) with the Alliance as that was the only language they had in common.
Do we change soldier's languages to meet the emerging requirements, or keep older, less necessary languages on the books?
How many guys can we get to learn a new language to a 2/2 standard every five years? Some will never learn an additional language beyond their native tongue to that standard, no matter what the investment.
And who can say what the needs will be in ten years?
Makes me glad to have been a 7th Group guy who spoke Spanish.
