(Answered UPDATED) Quad Mech - Firing When Down

[Tuhalu]

A situation came up in which a Quad Mech had its gyro and a leg destroyed in the same turn. About the only way this mech with a broken gyro could continue to be useful would be if it could still fire its weapons while prone (or if I had another unit that I could spot for).

The only relevant rule I can find is on page 113:

Four-Legged ’Mechs: A prone four-legged ’Mech (provided it has 4 legs, and has taken no hip critical hits) fires as though it were standing; the +2 to-modifier does not apply.

Can a Quad mech that has lost a leg (or taken a hip critical hit) still fire while prone, albeit with the +2 modifier, or must it stand to fire its weapons?

It fires with the +2 modifier.

This answer is being updated to bring things into line with the BMM.  The exact wording (which will also appear in a future TW printing) is:

"Provided it still has all four legs, and has taken no critical hits to any hip actuator, a prone quad ’Mech fires as though it were standing (the +2 modifier for firing when down does not apply, and it may fire leg-mounted weapons)."

So a prone quad can either fire entirely as if it were standing (all weapons, no +2 mod), or entirely as if prone (no leg-mounted weapons, +2 mod, just as a prone biped mech), but it never splits the difference.

Paul is correct in that any mech in general can fire non-leg-mounted weapons if prone--quad or not, damaged or not--but there was some confusion as to what this meant for quads combined with some other answers so I decided to update this one.
