I won't be able to give you definitive numbers with respect to the sizes because I don't have the numbers for CSE. That's not within my area of responsibility.
With respect to the importance of the two teams working together, as I had previously indicated, the teams work together day in and day out, every single week. We have embedded personnel in each other's teams so that we understand each others' techniques, tactics and policies and can best support each other to meet our respective operational requirements.
At the various levels, we meet regularly. I meet with my CSE counterparts on a weekly basis in certain meetings and more globally on a monthly or quarterly basis. Those relationships are absolutely essential to ensuring that both organizations have the tools and the capabilities available to each other.
