Town (San Hieronymo Peninsula)

Truck demolition
There are several trucks to take out here in different areas of the map. It pays to think tactically as an explosion will cause an alert making it harder to get to the other trucks. use different members of your team to place tnt on each truck. it helps to place the tnt underneath the truck as you can easily hide from patrolling guards and it is unlikely to be found. It is helpful to hide some distance from he truck to make it easier to hide after the explosion. Then swap to another soldier until they are all in place. This means that as a truck is blown up you can instantly swap to another location and your ready for the next truck.
