Final answer:
Before editing a Member's MGIB election, one must be an authorized personnel with the right to access and change the Montgomery GI Bill program records, and then follow the official procedures for amendment.
Step-by-step explanation:
To edit the Member's MGIB election, you must first have the appropriate authorization or access rights to make changes to a military member's Montgomery GI Bill (MGIB) program selection. This would typically require being an authorized official in the U.S. Department of Veterans Affairs or other designated personnel management structure. After gaining access, you may need to follow specific protocols and procedures to amend the election, which could include submitting a formal request or completing necessary forms.
