Hi Gonzalo - very glad you had fun with it so far...here you go:
- Op. Fire and Indirect fire units: Can this type of units perform Oportunity Fire? I'm playing without doing that, but not sure.
Not unless they are on their direct fire side (column). Black FP units don't have fire zones to be triggered.
- Sustained Fire: imagine that a unit with a HMG fires with Op. Fire while defending in an assault attack, and a Sustained Fire marker is placed. Can those units fire again to the same assaulting units? or is the Sustained Fire to remark that the units could fire to other adjacent hex triggering the Op. Fire?
No to the first - you have to have your Op Fire triggered again to fire again. Yes to the 2nd. If it couldn't sustain fire, you would put a No Op Fire marker on it - it wouldn't be able to op fire until removed.
- Night Assault Op. Fire and Infiltration: I have read that Japanese units can perform night infiltration within USA fire zones without being fired by Op. Fire, but, Can be this also applied to night assaults? Of course without Illumination markers present. As far as I know for what I read on the rules, the defenders always can fire. Correct?
Unless they have a No Op Fire marker on them, yes.
- Direct Commands: I thought that Direct commands points activate one by one your units, but it seems that you can pay additional command points to add units to a Fire action done by the activated unit. That's good for the americans. On the other hand JP units cannot do it with the Gyokusai marker, as they need to move or assault (I think they cannot perform the 2nd automatic action with the Direct Command chit, so they just assault or just move).
The units adding to your fire strength are also activated - that's why you have to pay for them too. Oh, and you can't perform a 2nd action with a Direct Command chit ever. You only get a 2nd action with a division or formation activation.
