From the story:
"Reduced health care benefits could save $2.4 billion over 10 years."
Question: How do you "save $2.4 billion" without cutting benefits? Answer: You don't.
If you read the story, you will see that they think by paying soldiers cash in return for a different plan that makes soldiers more cost conscious that it will save money.
Sorry you have a reading comprehension problem.
"Question: How do you "save $2.4 billion" without cutting benefits? Answer: You don't."
