The  Official Google Blog has announced that they have launched a new program where active U.S. service members who have a .mil email address can get a Google Voice invite within a day!

It’s not easy to stay in touch with friends and family when you’re fighting in a country thousands of miles from home. I spent 13 months in Iraq as an Army journalist where I flew in Black Hawks over Balad and Baghdad working to generate news coverage about my fellow soldiers. The whole experience was physically and emotionally draining, but it was especially difficult when I called home at the end of the day and nobody was there to answer.

For servicemen and women who are constantly on the move, having a single number and an easy way to retrieve messages from loved ones can be invaluable. To help our service members communicate with their loved ones and show our support to those serving our country, Google is launching a new program. Starting today, any active U.S. service member with a .mil email address can sign up for a Google Voice account at www.google.com/militaryinvite and start using the free service within a day.

This is great news for our active servicemen and women, especially if you own a BlackBerry. If you’re an active service member who owns a BlackBerry and is planning to get a Google Voice account, be sure to check out the Google Voice BlackBerry app.
