EuroGamer have posted a review of Operation Flashpoint. They also think that this is the web's first comprehensive review of the game. Here's a taster:

    "Over the course of the game's lengthy single player campaign you will spend most of your time as a grunt called Armstrong, gradually rising through the ranks until you have command of your own squad, able to give orders to your fellow soldiers and select equipment load-outs before missions. But you will also get to take on the role of an elite special forces soldier going behind enemy lines to steal documents and weaken defences, a rookie pilot flying close air support missions in A-10 tank busters and helicopter gunships, and a trainee tank commander battling against Soviet armour."
