The chainsaw used by today’s ForestryMechs and Support Vehicles like the GM Pathmaker series is a powerful upgrade to the same kind many woodsmen keep in their backyard sheds. This larger version, reinforced and upgraded in order to take on a broad mix of exotic flora—including the infamous Kaumberg oaks, said to be nearly rock-hard after a solid decade or two of growth—is tough enough to maul battlefield armor. Despite this fact, and the niche popularity of armor-rending chainsaws on the Solaris game vids, this device makes for a clumsy, desperate weapon at best. Chainsaws are thus a rare sight on the battlefield, never appearing among ’Mechs or Combat Vehicles belonging to regular armies. Like their Clan counterparts, Inner Sphere military commanders prefer to use the right tools for the right jobs.
A chainsaw can be used to make a physical attack.
A chainsaw can clear a path through wooded hexes. Instead of having to make multiple weapon attacks and track Terrain Factor, using a chain saw simply takes two turns to reduce a wooded hex from its current state to one lower; heavy woods become light woods, and light woods become rough terrain. Two units can combine to reduce this time to one turn.
While clearing woods, the unit must remain in the hex, though it can make facing changes as usual. It can also make weapon attacks, though all shots receive a +2 modifier as though the unit were moving at Running/Flank speed.Buildings:
A chainsaw attack inflicts 1D6 points of damage (in addition to its standard Damage Value) to a building hex.Support Vehicles:
Two Support Vehicles mounting chainsaws can reduce a wooded hex in one turn.
The chainsaw mounted on a Support Vehicle can also be used in a charge attack with a +1 to-hit modifier, plus applicable movement and terrain modifiers. A successful attack inflicts 5 points of damage to ’Mechs, vehicles and battle armor. Against ’Mechs, use the appropriate Kick Location Table or the appropriate full Hit Location Table if the ’Mech is prone. Against conventional infantry, the chainsaw delivers 1D6 damage; this damage is applied as though the attack came from another infantry unit.
Note that Hover and WiGE units may not use a Chainsaw unless they have first landed (stopped in the previous turn and spent 0 MP in that turn) and are adjacent to the target.
