The idea is that the players (not the GM) is sending AFs out to search for TFs.
As part of the orders, the players need to have actions (contingencies) for what the conditions are.
Written orders would be something like this:
Condition 1: Don't break radio silence, continue to observe/shadow until condition 2 or better.
Condition 2: Report back numbers and continue to shadow. Maintain radio silence and only report back every 3 hours. Break off shadowing if attacked.
Or something similar. Note that the QM mastered rules are pretty good about differentiating between GM actions/responsibilities, and player actions/responsibilities, so keep that in mind, and the context might make more sense for some of these rules.
