The 36-year-old, whose life was cut short by a Taliban suicide bomber Monday, will be sorely missed by her family -- a four-year-old son and wife.
Vorderbruggen died on the eve of the fifth anniversary of the repeal of "Don't Ask, Don't Tell," a policy which barred openly gay men and women from military service.
According to the US media, Vorderbruggen fought for the repeal by doing advocacy work.
"We can take small comfort in the fact that they will be extended the same rights and protections due any American military family as they move through this incredibly difficult period in their lives."

Vorderbruggen was killed alongside five other US soldiers by a motorcycle-riding Taliban suicide bomber during a joint patrol with Afghan forces near Bagram, the largest US military base in Afghanistan.
The Taliban claimed responsibility for the assault, which underscored a worsening security situation a year after NATO formally ended its combat operations in Afghanistan.
