A more thorough explanation:

Military allotment is a deduction from the salary of a parent who is on active duty in the United States military and is paid to the other parent as child support. This is a legal process that ensures that the child receives financial support from both parents.

For example, if a father is in the military and has a child, a portion of his salary will be automatically deducted and sent to the child's mother as child support.

This process is important because it helps to ensure that children receive the financial support they need, even if one parent is in the military and may not be physically present to provide for them.
