The Defense Department says that only about a quarter of the troops sent a survey on gays in the military have responded.
Pentagon spokeswoman Cynthia Smith said Thursday that close to 103,000 service members have completed the survey, which asks questions like how they would react if assigned to a room with a gay person.
The Defense Department had delivered 400,000 surveys to troops as part of its study on how it could lift the ban without hurting morale. The deadline to respond is Sunday.
Smith said 150,000 surveys will be sent to troops' family members later this month.
