I recently ran a one-shot Traveller merc adventure with a similiar set-up. Basically the team was inserted just over the FLOB (forward line of battle) and had to hoof it to thier target. Luckily for them there was transportation there for their return.
I've experienced the whole, get inserted and hoof it to your objective myself as a Cav Scout, not a SF-type, so I know it can be done.
Almost forgot, the team had to manuver to thier objective, avoiding known enemy locations and avoiding patrols.
