Memoir '44: Terrain Pack

A unit entering a Minefield must stop; an enemy unit then reveals it and rolls dice equal to its strength, scoring hits for its own symbol or grenades. Friendly units ignore their own Minefields, and retreating units may move through Minefields without stopping or rolling for hits (p. 8).

Yes. Units may battle on the turn they move onto an Oasis or Radar Station, although entering an Oasis or Radar Station still ends movement; Infantry may battle after entering a Marsh, but Armor cannot battle on the turn it moves onto or out of one (pp. 4, 5, 12).

An ordered unit that starts on a Road, moves along it, and ends on a Road may move one additional hex on the Road. This bonus does not automatically prevent battling; for example, Infantry can move two Road hexes and still battle, while moving three hexes on a Road means it cannot battle unless a card changes the normal movement allowance (p. 6).

No. Mountains are impassable to Armor and Artillery, while only Infantry can move between connected Mountain hexes under the specified Hill-to-Mountain or Mountain-to-Hill restrictions; Lake hexes are impassable terrain to all units (pp. 6, 7).

Yes. Big Guns fire up to eight hexes with dice values of 3, 3, 2, 2, 1, 1, 1, 1. If a shot hits but does not eliminate or make the target retreat, place a targeting marker on its hex; subsequent Big Gun attacks against that hex roll one additional die, but the marker is removed when the unit moves or is eliminated (p. 14).

No. A landmark’s effects can vary by scenario, as described in that scenario’s Special Rules or Victory Conditions. For example, a Factory Complex normally acts like a Town and Village, but its scenario may specify different rules (p. 10; p. 11).
