Do Hidden Deployment units have a LoF of 360˚ ? https://infinitythewiki.com/Camouflaged_State A Camouflage (CAMO) Marker has a LoF of 360˚. When Camouflaged State is cancelled, its player must replace the Marker with the corresponding Model, facing in any direction the player chooses. https://infinitythewiki.com/Impersonation_State An Impersonation Marker has a 360˚ LoF. Camo (and Impersonation) markers have an LoF of 360˚, you can declare ARO to basically everything in LoF and place your model with LoF. https://infinitythewiki.com/Holoecho_State Holoechoes have an angle of vision of 180˚, established in the front half of their base. Holoechoes specify 180˚ https://infinitythewiki.com/Hidden_Deployment_State The Hidden Deployment State is a special form of deployment that allows the user to deploy during the Deployment Phase without placing a Model or Marker on the battlefield. In your Deployment Phase, write down the position of your Hidden Deployment Troopers in as much detail as possible (make sure to specify whether the Trooper is in Cover, Prone, etc.) in order to show your opponent when their State is cancelled and their position revealed. The Hidden Deployment State is automatically cancelled whenever the Trooper declares any Short Skill, Entire Order or ARO. The Trooper's Model or Marker will be placed on the game table, in the position you wrote down, facing in the direction of your choice. https://infinitythewiki.com/Cautious_Movement Troopers in Hidden Deployment are neither Models nor Markers, so they cannot react to a Cautious Movement even if they have LoF. Hidden Deployment units are specifically not markers, but 360˚ or 180˚ are not mentioned. "As much detail as possible" for deployment does not specify facing has to be included, so that doesn't help. They do have some sort of LoF according to Cautious Movement (before we open that can of worms) If I declare an ARO I can deploy my HD unit as a model to make sure I have the correct facing, but if to declare the ARO I need LoF how do I check it? Based on the initial deployment or with 360 sight like a Camo marker? I always played with HD having 360 LoF like a Camo marker, but got asked to show why it works that way and I can't find anything to support it. What am I missing?
Facing isn't determined until the state is cancelled and you place the mini on the table, this would imply that it's considered to have no defined facing while in Hidden Deployment state.
If hidden deployment troopers didn't have 360 decree LoF you could more easily create traps where enemy moves into reactive trooper LoF using 2nd skill. Keep in mind that camouflage is an optional skill, so Noctifier ML could abuse this trick. So let's all pretend that it's super clear that hidden deployment troopers have 360 decree LoF because the game breaks if they don't have.
