Obviously not a helo guy and I appreciate the direction this thread went. But, the comments above don't appear to be supported by history. I am reminded of Operation Normandy. Eight Apaches escorted by MH-53s opened Desert Storm by flying through/under the Iraqi IAD, much feared at the time, to fire 27 Hellfires and destroy a key node. I'd call that "high threat". And nothing had "gone wrong" at all. It was planned. It was a natural extension of the Cold War Army attack capability.
That was a very specific 'one-off' mission that had involved extensive planning but was not in a very high-threat area like many other places in Iraq at the time were, from what I know the sites were close to the border and while well defended were not deep in the middle of a dense SAM area.
Don't Army Apache guys still lay claim to Deep Strike? If so, then how can they not know the "real capabilities and limitations" of their aircraft and the reality of the air defense game? They have done it before with great success.
If the Apache guys are laying claim to a 'deep strike' capability I am not sure that it means what they think it means. They did attempt two 'deep attack' missions during OIF and the first, the 11th Attack Helicopter Regiment tried to attack units of the 'Medina' Republican Guard division near Karbala on the night of 23 March, was a complete disaster. Reading a summary of the operation in the book
'On Point: The United States Army in Operation Iraqi Freedom' highlights how ill-prepared the Army was to conduct that kind of large strike into a high-threat area. Their plan was to attack the enemy in an urban area at very low-level at night, their support for the mission consisted of firing off 32 ATACMs for SEAD......and that was it. Thirty-one Apaches took part in the mission and were met at the target area by a large volume of small arms and AAA fire. Of the 30 Apaches that made it to the target area (one crashed on take-off) 29 came back with battle damage and the remaining one was shot down and the crew captured. It took a 30 days for the unit to repair the damaged Apaches and recover to full strength. As it said in the book it is a testament to the Apache's durability that 29 Apaches made it back with the battle damage they recieved. And after all that they never found the tanks they were looking for.
The second 'deep attack' by the 101st went much better with much more support, but even then they were close enough to the friendly forces that a large part of the support they got was from artillery. The Army's 'deep attack' definition seems a bit different than what we would think of as 'deep'.
