During a recent Apollo game, our PO was stinging at fort after comms was triggered. The line of agrons, walking along the north wall, were hit and a large number of them, being almost dead, decided to burrow en masse. The recon on the team, naturally, spammed surveillance flare over the area and asked the PO to kill the burrowed agrons. The PO repeatedly stated that he could not see them. Now it's possible that the PO was simply terrible. However, another player also stated that he could not see the agrons, so I decided to ask about it here. During the ensuing discussion, somebody stated that you require 3 perception in order to see units that are revealed by recon flare. First of all, I have no idea if this is true. I do know that I could see the burrowed agrons, but I always have at least 5 points in perception for wraiths/general line of sight (the PO in question had 0). So my first question for those more familiar with game mechanics is this: what is the perception requirement (if any) for being able to see units revealed by the recon flare? Secondly, the recon flare description states simply that it "reveals area for 10 sec to all players. Also reveals invisible units". My previous assumption was that recon flares worked just like shorter duration ranged road flares, which DO reveal invisible units to all players (at least, in my experience). If this is not true, is there a reason for it? Thanks. I could find no mention of any of this in the wiki.
