mine layer
 

Another shower idea, written up before playtest or research. ;)

A mine layer is a piece of optional equipment, that adds 1 to the armor or infantry cost of any mobile unit.

A unit with a mine layer can forego its movement for one turn, to lay a mine rated at the unit's movement.

The mine attacks the next unit to pass into the hex, at strength rating-to-1.

For example, a player spends 4 infantry points on a 3/1 infantry, with movement 2, and a mine layer. On every other turn, the player may halt this infantry for a turn, to lay a row of mines up to two hexes apart. The first other unit to enter any of these mined hexes suffers a 2-1 attack, which removes the mine (whether the attack was successful or not).

Here is my minefield rule set we use in our gaming group.

Here are the counters for mines and minelayers. :)
