You're going to push hard for metrics on something that requires activity on a number of levels, from procurement to procedures, tactics, and documentation. In NATO the interoperability is enhanced by a well-greased series of things that bring interoperability to bear. We're a part of all those dialogues. We participate in meetings. We participate in writings of the STANAGs. It's a fundamental level.
This is what we saw in Latvia. It comes down to people as well—people being interoperable with each other. That's something Canada does really well, with Wade Rutland again, bringing six nations together to work with each other: there are different languages to overcome, and different tactics, techniques, and procedures. Even at the parade at which they started their operation, there were different marching skills, some brought weapons, and all those things. We made it work.
It's a complex problem. In terms of metrics that make it easy to understand, it requires some time to explain in the right way, because of the complexity.
