Mark Nelson and Geroge Beccaloni

1. All the standard rules of Diplomacy apply (1971 rulebook), except where amended below.

2. Each of the major powers has a stockpile of land mines, sufficient to lay 5 minefields, and also 7 “bridges” capable of destroying minefields.

3. Mines and bridges do not need to be transported by a particular unit.  They may be laid in any location by an army unit belonging to the owning power.  One unit may lay any number of minefields or bridges, until the stockpile is exhausted.

4. Any unit which enters a minefield is immediately destroyed including units of the owning power.  Once the mine is detonated the mine is also destroyed.  Supply centers are unaffected by the detonation of a mine, though, any unit built on a minefield will cause detonation and be destroyed.  There is no restriction on the number of minefields which may be successively constructed in a particular province.

5. As a unit moves to another province, it may be ordered to lay minefields behind itself, in the province, it has just vacated (eg A(Mar) LM-Bur).  All mine laying is carried out in secret.  If the mine laying is stood off no mine is laid.

6. When an unit enters a province, it may also be ordered to lay down a bridge [e.g. A(Pie-B(Mar)].  This will destroy any minefield present, whilst the bridging unit remains unaffected.  Since the supply of bridges is limited they should be used effectively.

7. The laying down of a bridge is not reported in the adjudication, although the detonation of any will be.
