IceBreakingWeight=6


[MYHVYTNK]  ; synthetic UnitType
Weight=6    ; equal to the threshold, so it breaks the ice rather than cracking it

The figure is compared against the crossing type’s Weight, a bare number carried by the type definition with no unit attached. Arrival runs two weight tests in order, and the second is reached only where the first fails:

  1. weight at or above this figure — the ice is broken open into water;
  2. otherwise, weight at or above IceCrackingWeight — the ice is cracked;
  3. otherwise, the ice is left alone.

Both comparisons are at-or-above, so a vehicle whose weight exactly matches this value takes step 1. And since step 2 is only ever reached from a failed step 1, a vehicle at or above this weight never cracks ice: it either opens it, or — where the block below refuses to give way — leaves it untouched.

Only a vehicle runs the test, only in the snow theater, and only as it finishes arriving in a cell. Infantry and aircraft never trigger it however heavy they are, and a vehicle crossing on a bridge over the ice is exempt.

Breaking takes a two-by-two block of cells laid out ahead of the vehicle’s facing. Every cell of that block must already be water or ice or nothing happens at all; when the block does give way, all four cells take the broken edge tile of an ice set picked afresh for each cell and the ice around them is re-dressed to suit. Vehicles standing on the block start sinking and are stunned, infantry and aircraft on it are removed outright and fire the destroyed events of any trigger attached to them, and each affected object leaves a wake animation behind.
