This has been WAAAAY too late in comming.
Not to use hollywood as my source here, but anyone who'se heard the phrase "get someone on that .50" from the memorable scene in Black Hawk Down knows our boys need protection.
I have always been and always will be a proponent of giving some of this life saving technology every single other unit of the millitary gets to our infantry, the unit that takes 25% of all casualties. For the love of christ, the police officers that hand out chicken-**** traffic tickets are better armored than our men asked to get shot at by 7.62 every day.
We spend $100 million a piece on every single F-22. The least we can do is give our boys an updated rifel and some armor.
