Agree with baron
No judging here just helpful advice
I'm sure the boys in TBS can help personally if you get stuck along the way and need some in person help but besides wat baron has mentioned already you need to check out pandatroopers build threads , outstanding !!!
Also remember to go for officer before SWAT some things are different for approval ,
Like if you build swat straight up you might have to change things to get PO then change back for swat,
As for rarity of SWAT member , it's just how many want to go that extra mile , not all do, and no one I can think off hasn't got there eventually or has given up 1/2 way
You can do it mate
You sound like you've got a good head and are gunna take your time so can't see there being any problems
Everyone is here to ,and will, help
Welcome brother your among friends
