Housing and food allowances come in the paycheck, even for those who live on base (but in a very reduced form). However, if he lives off base, that money will not come, as it is divided up into the bi-monthly paychecks military members receive. Even for those who live on base and use the galley/chow hall, they still need at least a little bit of discretionary income. Uniforms don't pay for themselves, and the allowance a service member receives is only doled out once a year. There are payments that automatically come out of a service members pay, such as life insurance, that will not be paid on time and will be incurred as a debt. Many service members have vehicles and insurance on them, even if they live on base, and many have those payments come out as an allotment each month. Without being paid, these payments will not be made, causing late payments and fees to build up with lenders. The SCRA does not have provisions in place to cover such things.
I'm lucky in that if those on the hill cannot come to an agreement here shortly, my retirement and GI Bill payments will not be affected. However, many of my friends are active duty or reservists, and their pay will disappear for an unknown amount of time, pay that they rely on completely to live. The area I live in is highly dependent on the military and other government money that runs through it. Losing that money, for even a relatively short period of time, will cause a large impact. The region, while still affected by the recession, has not been affected as badly because we have that large influx of government funds. I can't even begin to imagine the effect of losing that money will have on the local economy here.
The largest business and employer in America is showing their incompetency in managing themselves, and in doing so, punishing the citizens of the country.
