Type (Category):  Equipment (Other)

Description:
A technology as old as the widespread use of minefields in Terra’s World Wars, minesweepers are designed to detonate mines at a safe distance in front of the vehicle, clearing a path for other units.

Game Rules:
Minesweeper equipment begins play with an effective Armor Value of 30 points, though the equipment cannot be used as additional armor and will not stop attacks against the Minesweeper vehicle even if the attack passes through the sweeper’s facing arc. Maritime Minesweepers are effective only against sea-type minefields; Land Minesweepers are effective only against land-based minefields.

As their name suggests, Minesweepers operate by simply moving a minesweeping vehicle through a mined hex, but their effectiveness varies with the minefield. A Minesweeper can be either activated or deactivated in the End Phase of a turn. Only activated Minesweepers clear mines.

If the hex contains a vibrabomb minefield, the Minesweeper will automatically set off and clear the field if the sweeping vehicle is within 9 tons of the minefield’s tonnage setting, taking 10 points of damage to the Minesweeper equipment.

Against active, Inferno and standard (conventional) minefields, the player controlling the minefield must roll a normal mine explosion check upon entering the mined hex, but will set off (and clear) the mines with the sweeper on a result of 6+ (sustaining 6 points of damage to the Minesweeper equipment); if multiple mine types are located in a single hex, this roll must be made for each type of minefield. If this roll fails, the minesweeping vehicle itself may still set off the mines under the mines’ normal rules, but sustains any minefield damage to the Minesweeper’s location rather than to the Minesweeper equipment itself, and leaves the field active per the mines’ standard rules.

Minesweepers have no effect on command-detonated minefields. A vehicle may only mount one Minesweeper per hex that it occupies.

Minesweeper equipment remains fully effective until its “armor” falls to 0 (or less), at which point the Minesweeper is treated as a destroyed item. Damage in excess of a minesweeper’s Armor Value transfers automatically to the location where the sweeper is mounted.

Special Unit Abilities
The special unit abilities described here are intended for use with the Alpha Strike rule system:
 Minesweeper (MSW)
A unit with a minesweeper automatically clears any minefields it is in base contact with at the end of the Movement Phase. During the minesweeper’s Combat Phase, it may not execute any attacks, but must roll 2D6 to clear the minefield, applying a +4 modifier to the result if the minesweeping unit is not infantry. If the result is 10 or better, the minefield is cleared and removed from the map. If the result is 5 or less, the minefield detonates for its full effects. Any other roll result means the minefield is not cleared.
