(Success Numbers) Weapon Type:
Flamer 4+,

Modifiers for terrain to those bths are as follows:
Woods/Light Buildings no bth mod,
Med Bldg +1,
Heavy Bldg +2,
Hardened Building +3
A unit attempting to clear a wooded hex runs the risk of setting fire to the woods accidently.
To represent this risk, the player rolls 2D6 before attempting to clear.
If the result is 5 or less, then the woods catch on fire.
If a weapon attack against a unit occupying a wooded hex misses its target and
the weapon can be used to start fires (weapons listed above),
the attacking player rolls 2D6. On a result of 2 or 3, the hex catches fire.
Buildings can't accidently be set on fire.
