I suspect they are going to have problems finding the right sort of Senior officers for the Engineers and REME. If they put it army wide.
A lot of ours could speak German at gutter level. But a lot of the Professional engineering trained officers who were highly talented in engineering and leadership really weren't skilled on there language side of their Brains.
Now there were a couple who were gifted in that area but realistically they needed watched like a hawk by the SNCO's when any sort of proper engineering decision was taken.
