  1. Was my CO in 08/09, need a chat with him about how we have now put 6RAR Afghan Veterans amongst the movie Danger Close, which is about the battle of Long Tan. Would love for him to be involved!

    He wants to rearrange some of the stupid decisions that have been made of late, concerning gender in the Regiment & gender rearrangement,, being paid for at public expense. Also fitness qualifications, for Infantry entry. The Regiment level seems to be on a very slippery slope, Duty First
