[...] players must declare which troop possessing the Forward Observer Special Skill from their Army List is their Liaison Officer. The trooper chosen must be always one of the models or Markers deployed on the game table. Players are not allowed to choose troopers in Hidden Deployment. Also, troops whose Troop Type is REM are not eligible to be Liaison Officers. At the end of the game, [...] make a WIP+3 Roll using the Liaison Officer’s WIP. If the roll is successful, the player will get 1 extra Objective Point (up to a maximum of 10 Objective Points). So you can choose markers and it has to be a Forward Observer. Do you choose the Ninja, skip Hidden Deployment and try to keep it alive? Do you invest in a Karakuri, even if it does not fit in your game plan? Do you choose the Keisotsu and pray nobody remembers that rule? Or do you completely ignore this extra?
