Thread: The word blancoed

In this Post (Here) The word "blancoed" is used, does anyone know the actual meaning of it?

The word is in this sentance;

In the middle of another mortar "stank" who should arrive but Major Gell, dressed as always with his equipment well blancoed, and he then went on his way.

Best I can do is "blanc" meaning white, but whited out equipment makes no sense....
We need them squaddies Kelly and Jamie !

Would agree with "Clean" going by the sentance tht was wrote.
