Modifier is based on available movement modified by heat level and critical hits, if applicable. Hex travelled is irrelevant. This modifier does not apply to aerospace units. Treat bogged down target as if it has a Target Movement Modifier of +0. Treat Climbing unit as if it has half its normal Ground Move, with no jump. Use the unit's Sprinting Move for the base target movement modifier. For battle armor targets, Stealth adds +1 at Short and Medium ranges, and +2 at Long range. For all other units, Stealth adds +0 at Short range, +1 at Medium range, and +2 at Long range. Includes fixed-wing support vehicles, conventional fighters, small craft and DropShips. Only applies when target is airborne. Do not apply if attacker is an airborne aerospace unit. Only if attacker is also underwater (or is on the water surface and using TOR special); all underwater ranges are halved. Target has intervening or occupied Woods t errain. Buildings block Line of Sight, providing either partial or full covers as a hill of equivalent size. Apply an additional onal +1 to-hit modifier er if target is an Infantry unit. If the spotting unit makes a weapon attack in the same turn as it spots, apply a +2 modifier instead. Fire Control Hit effects may apply multiple times. Does not apply to Physical attacks. Does not apply to Physical attacks. Not cumulative with the Attacking Indirectly modifier. Applies if target is transporting transporting battle armor as cargo, cargo, or using mechanized/extended mechanized/extended mechanized mechanized infantry specials. specials.

Airborne units (including Air vehicles and Aerospace units) ignore all terrain conditions until they attempt to occupy the same space and level of them (including attempts to land or liftoff). If airborne units attempt to enter terrain prohibited to them, treat the result as a crash. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17]
+1 Move cost for wheeled support vehicles without Off-Road (ORO) special ability. All Tracked or Wheeled units gain an extra 1 point of Move on any turn where the unit spends its entire Move on this terrain. Infantry units reduce Move cost to enter this terrain by 1 (to minimum of +0). Wheeled units with the bicycle (b) or monocycle (m) movement modes may move through this terrain. Wheeled or Tracked vehicles with the Amphibious (AMP) special ability can move on water surfaces at a Move cost of +1. Infantry units can move through water of any Depth only if they have the UMU special ability. This is the cost to move along the bottom of a water area. No additional cost applies if using submarine movement. IndustrialMechs can only enter water of depth 2 or greater if they have the environmental sealing (SEAL) special ability. Non-submarine units at this depth (including units with UMU special) may suffer damage. See Water (Expanded) (p. 67.) Infantry, ground vehicles, ProtoMechs, and WiGEs may not perform elevation changes greater than 1 level per 1 hex travelled. ’Mechs may not make elevation changes over 2 levels unless using Advanced Movement Modes (see p.62). Infantry units do not pay any additional Move cost for Buildings; ProtoMechs pay only +1 Move for all Buildings. Units in this terrain type may bog down and/or suffer damage. See specific terrain rules. Only ’Mech units apply the +1 Move cost in this terrain; all other units in this terrain apply +0 Move cost. Rail units in this terrain must move along the rail and pay +0 Move cost. All other units apply the +1 Move cost. Only infantry units and wheeled units without t he Dune Buggy (DUN) special apply the +1 Move cost in this terrain. Only ’Mech and ProtoMech units apply the +1 Move cost in this terrain; all other units in this terrain apply +2 Move cost. BattleMechs with the LG special reduce the movement cost by 1 in this terrain type.
