Smoke X
A unit that has the Smoke X keyword can make the Smoke X action to place X Smoke tokens comepletely within 1 and in LOS of its unit leader.
Smoke tokens cannot overlap any Objective, Advantage, Charge, or other Smoke tokens and must be placed on a flat surface.
Smoke Tokens
Trooper units whose unit leader is within 1 of a Smoke token improve the numerical value of their Cover by 1 during the Determine Cover step. While a Trooper unit is attacking, if the attacking unit leader is within 1 of a Smoke token, the defending unit improves the numerical value of their Cover by 1. Effects that improve a unit’s Cover are cumulative. A unit cannot be affected by the same Smoke token more than once. Smoke tokens are removed during the Remove Tokens step of the End Phase.
For example, a Trooper unit whose unit leader is within 1 of 2 Smoke tokens would improve the numerical value of its Cover by 2.
