Hello,
Regarding an omni mech transporting battle armor infantry with the MEC special, let's say an Elemental Point and a Viper for this example, a number of questions:
1. How close does the Elemental Point have to be to the Viper to mount it? Base to base seems implied.
2. When dismounting, is this also base to base?
3. Can the Elemental Point use jump movement the turn it mounts/dismounts (I understand it would still count as having used ground movement after it dismounts)?
4. Can the Viper use jump movement?
5. Is this a legal sequence? During the movement phase the Elemental Point activates first, and jumps 4 inches to be in base contact with the Viper, the Viper then activates and the Elemental Point Pays 2 inches of (jump) movement to mount the mech. The viper then jumps 16 inches and dismounts the Elemental, the Elemental is dismounted both in base contact with the Viper and also to an Enemy unit. During shooting the Viper acts normally, the Elemental may make physical attacks (including anti-mech) only as it is in base contact with an enemy unit.
