mr. krepinevich: you said it right, senator. senator ernst: thank you, i apologize. mr. krepinevich: that's all right. it goes back, tell me how you're going to fight. the krepinevich strategy over the next 20 years, the big growth in ground forces is rocket artillery, coastal defense, and striking. that's going to be essential to having effective defense of the first island chain. so i think in terms of an operational reserve or a second wave force or reinforcing force, national guard to perform a function there, in the persian gulf, if we were, i think the forward of course has many capabilities that would support it. but also if we have to have an expeditionary force there, you have to mobilize a certain amount of force. again i think support major growth area for there would be rocket artillery in its various forms. in eastern europe if you buy my idea that trip wire forces, we're going to need because of limits on finances and manpower and so on. if we were to develop our own anti-access area in yeern europe, we would be relying on those kinds of systems as well.
