I start Basic on Monday and got everything on the list and am now wondering how particular the guys there will be. 1) Swimming trunks or speedo? Goth both, not sure which I am meant to take. 2) With the bungee cords a few are tri-colour (Black/Khaki/Dark green)- will they be ok or do I need to replace them with dark green specifically? If it is relevant ATC Pirbright.
