Hover Mode:
The assault ship is subject to all the rules for Flyers. In addition
it may hover indefinitely by going into a "hover mode" any time during its
move while on advance orders. While hovering, it may be placed on First
Fire orders and provide in-direct fire support. There are three different
Hover Modes:
NOE:
The assault ship is Considered to be at tree top level (height of
small building, or just above the trees) and any unit firing on the
assault ship receives a +2 to hit die roll modifier(DRM). This is
because the assault ship is a very, very large target(roughly the
size of an emperor titan), and the fact that the assault ship is not
moving. While at this height, it can be been seen (and see) by all
units with LOS to it.
Low:
The assault ship is considered to be just above the buildings level
(above table top like skimmers) While at this height any unit firing
at the assault ship receives a +1 to hit DRM. In addition, the
assault ship may only be close combated by flyers, skimmers, and
units with some type of jump pak(i.e. swooping hawks, assault marines,
etc.)
High:
The assault ship is considered to be high above the battle field.
While at this height, the assault ship may only be close assaulted
by flyers and skimmers. The assault ship follows all the rules for
flyers at high altitude. in addition to thoughs rules, any skimmer
that `pops` up or flyers in high altitude, will receive a 1+ to hit
DRM.
While in any hover mode the assault ship may unload assault marines (or
any skimmer, jump pak type of model) via the assault ramp, this is provided
the ramp is not damaged or destroyed. Models unloaded in this manner may
depart during the movement phase of their sides turn . They may move 15cm
if the hover mode is NOE, and 10cm if the hover mode is low. At a hover
mode of high, they just simply plunge to their deaths, no you may not drop
them on things. This move is considered "charging" so they may move into
close combat.
