Pulling out the EBT and their Military Star Card to pay for groceries, not just the retirees and Veterans (now able to use the DECA stores, as in Post Exchange and Commissary).
Generally, it's military members with larger families who are E-3 and below (with the occasional older O-1 or O-2 who joined in their mid-20's with multiple dependents...) that require EBT assistance. Basically, people who are supporting three or four people while still in their first four years of service, not eligible for a larger Dependent subsidy because the default position is that the majority of persons joining the military are in their late teens/early 20's and typically not married or require any residence larger than a studio or one bedroom to comfortably live in when not deployed.
The DECA Commissary is a godsend for young families - baby supplies that aren't very close to expiration dates, such as Infant formula, baby food, disposable diapers, and hypoallergenic personal and home cleaning items are still around 2019 prices.
Food is relatively healthy, and about 1/2 to 2/3 the cost of food on the outside. They still have trained and certified produce and deli managers, at least one butcher, and an in house bakery that's usually pretty good.
The Exchange doesn't have a profit margin to meet (which privatizing DECA would introduce); it generally carries quality name brands 10% to %20 below MSRP and customers don't have to pay local and state taxes, typically a 5% "fee" that goes to the Military's welfare and rec overhead budget.
But even with those discounts that DECA provides, junior enlisted and a few junior officers still need assistance to feed their dependents.
Just as local Teachers and EMTs should have assistance, because they're obviously taking on simple jobs that are nothing more than a simple service; interactive babysitting or being a taxi driver for sick people "for the love of the job", instead of "real" job computing to accumulating as much money as one can...
