This is a tragedy for our country. It is so sad to fight in wars overseas and then come home to be killed by violence. I'm praying for the many families involved in this tragedy. And I thank them for all that they've done to make this world a safer and better place to live. God bless them and God bless America

We are so very sorry for this terrible loss of lives. Let's try to prevent future tragedies by effective gun control laws. We don't need such weapons of horror which can kill and maim so many people in such a short time. In a more peaceful world this might not have happened.

Has Fox News blamed this on Obama yet?

My family's prayers and thoughts are with you all.

This is all just too terrible

Thoughts and prayers for family members of those who were murdered and for those who remain fighting for their lives. I can't get my head around getting killed serving our country on a military base in our country. Peace.....

Words cannot express the sorrow felt across the country tonight.

sending all my prayers to the friends and families of all.

My heart goes out to those lost while serving their country.

I hope this encourages our nation to take our soldiers' mental health more seriously.

What a tragedy. Such a sad day in America. God Bless those killed and wounded and their families. Our prayers are with you all.
