A vehicle may not enter a hex containing a tank trap marker unless it started its movement in an adjacent hex. As soon as a vehicle enters a hex containing a tank trap marker, it must end its movement. Vehicles on a tank trap may move off the tank trap hex normally. Squads are unaffected by tank traps.
Tank traps give squads in the same hex +1 cover.
There may be a maximum of one tank trap marker per hex.
