The past couple days I was privileged enough to trade links with a couple of well established milblogs: A Soldier's Perspective and The Military Observer.
A Soldier's Perspective (ASP) is privately operated and is designed to provide personal information, views and commentary about the military. CJ, Marcus and the guys provide great commentary from a Soldier and Marine point of view.
The Military Observer is owned and operated by Andrew Lubin. Andrew is a writer, author, speaker, and historian who follows events in the Middle East and Central Asia. This is more than just an academic exercise for him: Andrew's son is in the Marine Corps.
Both sites deserve more than a cursory glance and offer tremendous depth and insight.
