Infantry pressed forward, again trying to attack with rocket launchers, but could only achieve relatively minor effects, unable to deliver a decisive blow.

If dripping water can wear away stone, then imagine the effect of thousands upon thousands of various bullets and artillery shells smashing into it.

Another plan was to blast it with 155mm howitzers.
This was a reliable approach; a couple of hits, or even a single direct hit, might well be enough to accomplish the mission of destroying it.
