Overall explosives feel good but there is inconsistency in their power, operation, and reactivity to other explosives or resource points.
landmines are great at taking out an entire building but they seem to struggle with trying to cause chain reactions or interacting with charges. Often trying to place charges on the ground will place the stick below the floor. A single charge doesn't blow up a landmine, often if the charge isn't in the exact right position they don't do anything. Likewise charges often are not enough to take out a building on their own without using a large amount of them. i haven't checked the exact number, but i feel that they should be more effective if spaced through a building. It would be nice if charges and Landmines had more interconnection. Having a simpler interaction for placing a charge directly on a Mine or Mortar shell as a sort of IED would be very useful.

Building destruction works well for the most part. The general feedback i have found is that it's a great first step and changes the game in a positive way but that players want more sectional destruction in the future where walls can be taken out or holes blown out of barns. No one is expecting full scale Frostbite style destruction, but that's still what is often cited as a "gold standard" or used as a comparison.
Some of the issues with destruction include if you build compositions too close to a building and destroy the building, the composition will get taken underground with the building making it inaccessible.
