Apaches don't attack an attacking tank force from behind, they attack from behind a terrain feature. They hover behind a rise while recon choppers, Baby Bells, scout out enemy formations...Longbows do this with built in radar. They then pop up long enough to target, lock on and release, at which point they hide back down. When ammunition is down or the enemy is to close, they scoot back behind the friendly armor.

A few years ago I was driving from Arizona toward Las Vegas and saw an Apache (obviously on a training mission) suddenly pop up from behind a small hill about 20 yards away, pause for a second or three, and drop down just as quickly. I wasn't driving, so I craned my neck and looked through the back window to see if I could spy the Apache as it negotiated the terrain. Nothing. It had simply disappeared.

I was impressed.
