What BAQ code is assigned to a member married to another member with a dependent child under 21?

The BAQ code assigned to a member who is married to another member with a dependent child under 21 is W. This designation specifically reflects the housing allowance considerations for military personnel who are in a dual-member family situation.

Service members who are married to other service members, especially with children, may have different financial needs and considerations for housing allowances compared to those who are single or not in the same family unit. The W code acknowledges the unique circumstances of these families, including the cost of living and housing for dependents.

To help understand the context further, the other codes are typically used for different family or marital scenarios and do not appropriately apply to situations involving two service members with a child, which is why they would not be applicable in this situation.
