Supermen Infantry?

If you have a chance to pick up Osprey's new book on VC and NVA fortifications and tunnels by Gordon Rottman I would recommend it. 3 miniguns from 1000 feet plus would not have done a thing to a VC spider hole, and from how the fortifications in Rottman's book were described, US military planners themselves ran into the problems you are describing.

Hits from 750 lb. and 1,000 lb. bombs, with their crater only 6-10ft. from bunkers, left them intact. Walls and roofs did not even collapse...One example is a triangular 12.7mm AA machine gun position. A 750 lb. or 1,000 lb. bomb landed directly in between the three pits, creating a 20ft.-diameter, 10ft.-deep crater; the pits were 36-60 ft. apart and remained unscathed. There were 2-3-man fighting/living bunkers within 10ft. of 38ft.-diameter, 18ft.-deep craters - and the bunkers survived.

The general conclusions concerning the effects of artillery and air strikes were summarized in a study as follows:
*NVA bunkers withstood anything but a direct hit by artillery or bombs.
*Delay fuzing produced the best effects against bunkers; however, much of the ordnance penetrated too deep before detonating in the soft soil.
*Super-quick fuzing was effective for stripping away camouflage to expose positions, but was not effective against bunkers.
*Napalm was not effective for burning off large areas of foliage. WP artillery rounds were more effective.
*105mm and 155mm howitzers were not effective against bunkers.

So from that you see that in the realism department the scenarios you describe might not be too unrealistic.
