In defense of the troops:
The military has taken a special interest in the bill because servicemembers are a favored demographic for lenders making small, unsecured loans at high rates. The industry's critics complain those lenders cluster near the gates of bases, often using flags and military-sounding names to make them seem legitimate or even sanctioned.
They may be professional soldiers, but they're just as vulnerable to financial scam artists as anyone else. Maybe even moreso, because they're often based a thousand miles away from home, lacking the advice of family and friends.
