Narrative:

Flight abc from ZZZ to ZZZ1. Flight pushed back 150 yards from gate in steady snowfall with ramp covered in 3/4 inch loose snow. After deice/anti-ice, we needed gate-return to deplane will passenger. We never started engines. I called operations for a tow-in. Coordinated with tow crew and ground control and checked area clear. About halfway to gate, felt aircraft slide and saw marshaler in front of the tug signaling an emergency stop. I transmitted 'stop, he is signaling you to stop.' after stopping, I got no further responses from the tug driver. The left outboard wing had struck a deice truck. The truck was tilted up on 2 wheels and held by the wing. I notified operations and requested maintenance on the headset immediately for evaluation. Maintenance advised there was no damage to the wing fuel bladder area, and that no fuel was leaking from the aircraft or truck. The truck appeared to be firmly wedged under the wing and was stable. At this point, communications became very hectic with multiple calls on radio, PA, and cabin, and ground intercom. At some point, I believe I may have inadvertently been pushing the cvr erase button, as it is in proximity to the cabin and ground crew call buttons. All passenger were safely deplaned via stairs after the deice truck was stabilized with heavy equipment. Aircraft damage was limited to a dent in the #1 slat and an access panel.
