I find it particularly interesting how naval mines can be attached with a steel wire, which drags the mines towards the ship when it passes, and thereby creates a twosided explosion to it.
It's also noteworthy that in many occasions, a single mine of torpedo can sink a large ship, such as a carrier. Also, the wikipedia article seems to back the way the cost of mining and clearing them works in xta:
So, in light of this, I wonder if naval mines aren't in fact too weak in xta, as one mine usually only can destroy T1 units.The cost of producing and laying a mine is usually anywhere from 0.5% to 10% of the cost of removing it, and it can take up to 200 times as long to clear a minefield as to lay it
I only discussed naval mines, but feel free to discuss land mines as well..
