You do a couple of back-tracks, and no one seems to be following your trail. However, during the trip you come through a small ravine between a couple of hills in an attempt to avoid some other TIE fighters and you spot at the end of the ravine an armoured troop transport with the Stormtroopers doing some sort of work nearby. They spotted you before you spotted them, and several are moving to intercept you as you move out of the ravine. They have weapons held at the ready, but not in firing position.
[Perception] Turning around now will certainly alert them, and [Technical] the old truck won't be able to out run a troop transport.
The transport looks to hold about 15 stormtroopers. Four are approaching you, and you can see 3 more near the APC and 3 several meters away working on a piece of equipment, which leaves somewhere around 5 unaccounted for. Only the four moving to intercept you appear to be paying particular attention to you.
They are currently about 40m away from you.
None of the troopers appear to be particularly agitated or unusually alert, and they are moving with purpose, but unhurriedly to intercept.
