Yes I supposed it was to change it from Red to Blue but they do not have same heading so change was pretty visible from close escort :)
I surely did something wrong then, all I remember is the british calling lots of sam shoots and then nothing...
Thanks, otherwise I will find a youtube video to see what's next :)
edit : ok so after pushing green3 I should hear Saxon 1-1 calling Mudspike, but never got that triggered, don't know why
