Maybe I can shed some light to what the real world is like in an Air Assault mission. I spent 6 years flying helicopters in the Army, including the 101st (which shares the airfield at Campbell with the 160th) and have served with many of the 160th folks.
When you do an operation like that, like inserting LRSD (or LRRP for you old guys), or anything like that, you use as few aircraft as possible. You take all the information you can get, figure out where the best place is to land (actually the ground guys pretty much choose that within reason) and the best way to get there. Any recon unit is toast if they are compromised. If any get out alive, it's pure luck. You sneak in with a couple of ships (depending one what the team is) and drop them off. Later you sneak back in to a different place and pick them up. Hopefully just as quietly. If you take fire on the insertion, there's no reason to continue. If you're dropping off a recon team into a hot LZ, you've just killed those guys as sure as you've pulled the trigger yourself.
The days of shooting up "hot LZ's" with gunships and landing huge forces in the middle of a hail of gunfire went the same direction as the USMC and defended beach assaults. Yeah, you can do it, but generally there's a smarter way.
As far as the Chinook goes, it can be flown just as fast, low and "tactical" as any of the helicopters the Army operates. Just because it's the size of a school bus doesn't mean it handles like one. It's still one of the fastest helicopters we have. It has the best capability for high alttitude, and heavy loads. Don't let it's size fool you, it's just as responsive as any of the others. It's large size limits where you can fit it, but that's part of the planning process.
As for the 160th needing Apaches, that's like saying Delta needs tanks.
The bottom line is this was a normal operation, executed in a normal way. There's no guarantee that the LZ would be cold, or that in war the bad guys will not be where you don't want them.
