In Britain, you do your job. When you do an American TV show, there is a sense of being one with the crew, and there is a leadership element, which was a learning curve for me because it is very different culturally. In Britain, you just do it, leave and say, 'Thanks.'
Leadership has a harder job to do than just choose sides. It must bring sides together.
These days, it's often women in uniform - moms, wives, even grandmothers - who deploy and leave their families behind.
