Thanks!
The Ford ambulance was imported from the US. It wasn't used anymore by the original FD and Cascais VFD decided to buy it.
The Snorkel truck should have a similar story, but it was bought in the 80s (it fought the infamous Chiado fire, which occured in 1988). It was one of the two platform vehicles that RSB hadboth acquired during the 80s (a Renault and the Mack/Ford). Unfortunatly, one of the trucks (the Renault) crashed and became unrepairable. The Snorkel truck was left in a garage during years, untill the firefighters decided to unite and repair the unit. The unit is still being repaired at the moment, but it already has the new logos, which means that it'll return to our streets very soon.
The guys in the black suits are basically PSP's Personal Safety Corps: a group of GOE (Police Special Operations Team) operatives that are, basically, bodyguards. They'll be able to equip MP5s and will be important in atleast two missions. The other man near the Audi A8 is the VIP.
Awesome! Seems like you know your stuff.
