"Just last month, an audit by the DOD inspector general found that the Army is at risk of wasting up to $21.88 billion in taxpayer funds to build a system that soldiers may not want to use or use as intended," Shaheen said.
"And I understand the need to continue development and that the IVAS system is what appears to be the future. But I also understood that the [research, development, test, and evaluation] for that had not been adequately completed. And so we're investing in a system that we're not sure is going to work, and we're not sure we have enough of the old system or the current system to address the soldier's needs. So I'm really -- I'm not convinced on your argument."
