Seems like a co*k-up somewhere...you're practically useless if
you have knee problems since Recce gotta walk damn long
distances..... 
Better to
have your medical problem checked out first.
With your knee like this, you might even have problems getting
through CST; not to sound condescending, but I do know the
expectations, as a few forumers also do, about recce units....like
you, I was also from Guards.... 7 SIB BRC...sigh....good ol'
days...
