Any opinions regarding them, good or bad, would be appreciated. It costs 1 extra MP to use a crossing arrow. A unit may not use a crossing arrow if there is an enemy fleet in the surrounding sea zone. A unit may use a crossing arrow if an enemy corps occupies the area to be entered only if he has a friendly fleet in the surrounding sea zone. The idea of not ever being able to cross at a defended crossing arrow, even when one controls the seas, seems a bit extreme.
Numerical superiority ought to somehow figure into all combats.
Advance through Captured Territories Corps which are advancing through a territory that was captured on the same turn by a force that moved earlier in the turn, may continue moving through the captured territory by paying MP equal to those expend by the initial force in capturing the territory. If a NPC captures a province then the controlling or allied PC may not then garrison the captured territory with its own forces. A captured territory may only be garrisoned by the country that captured it. Any force that enters a winter turn without a LOC to a province in their home country will lose 1 division per corps. A LOC may not be traced directly from a blockaded port into the surrounding sea zone.
