Default AT Guns

I find it odd that the Soviet and WARPACT armies developed and deployed conventional anti-tank guns while NATO did not. I find it especially odd since Soviet-bloc armies were built for offense while NATO was preparing to fight largely defensively (on the ground, at least).

Why didn't NATO invest in an AT gun? I figure that it's due to the West's love affair with hi-tech weapons. It seems like they made a conscious decision to go the missile route and forego the more old fashioned gun. On a more practical note, I figure that a large caliber AT gun (in keeping with NATO tank guns, 105mm minimum, 120mm max) would need a larger crew than, say, a TOW launcher, and it would probably need a prime mover more powerful than a Humvee. AT guns are also larger and harder to conceal than most missile systems.

On the pro side, AT guns have a relatively high rate of fire (around 10 rounds per minute) and kinetic energy weapons (ie standard AP rounds) have a better tank kill ratio than HEAT rounds, especially against newer types or types fitted with ERA. Most ATGMs take quite a while to reload. For example, the M113 ITV can fire two TOWs but then takes several minutes to reload.

In many ways, the Soviets ushered in the age of ATGMs with the AT-2 Sagger. They still kept the AT gun, though.

Any other reasons the west skipped on the AT gun? Any significant NATO AT gun systems I might me missing here.
