Back in January, 73 percent of those middle-class military families said they wanted to be grandfathered in under the old system, up from 70 percent last October. The new changes seem likely to increase that percentage.

Those February changes weren’t at all popular, including as they did delays to contributions for younger servicemembers and ending matching contributions for career military after 26 years of service. And then there’s the little matter of personal discount rates, which would effectively lower lump sums way beyond what civilian retirement lump sums would be. The American Academy of Actuaries actually warned the Department of Defense about those rates in April.

But the plan wasn’t a rousing success even before those moves were announced, and now new moves are afoot.

While two of those changes are positive—one extends matching contributions for servicemembers who serve beyond 26 years, while the other increases the cap on government contributions to the Thrift Savings Plan from 5 percent of basic pay to 6 percent—the others? Not so much.

TSP matching contributions are now delayed from the third year of service to the fifth year, and the new system’s mandatory minimum continuation pay for all troops reaching 12 years of service has been removed.

First Command projected that, under those last two provisions, monthly retired pay under the 2017 proposal could fall roughly 5 percent short of that under the 2016 law, but the shortfall could be even larger.
