helicopter brigade. coming along with that is at least 4,000 people, pilots, maintenance, crew, fuel. so you talk about expanding that to additional battalions, different artillery battalions, and you quickly go from 130,000 to 150,000. and i think that's what the intelligence community has been watching over the last several weeks, several days of an increase coming into different attack positions or different assembly areas that would contribute to that number that we're talking about now. >> even with this increase, general, as you have looked at this, your opinion has been that you are not convinced vladimir putin will attack. why is that? >> i'm not convinced he's going to attack on a large scale, john. i think he's going to continue to try to probe. i think the interesting piece to watch for is what happens in the southeast part of ukraine and additional forces rolling into the donbas.
