Do the "Steal a Tanker Truck" mission in soldier jobs.
Ask your Mafia to give you one
It is the "Protect your City against a Rival Family" job in the Hitman job tier.
After attacking a property in mafia wars, it will give you an option to use a burner if you fail
Yes, you should join because more mafia members can give your more energy packs/boosts, gifts, and you get extra power when attacking someone else. You can add a lot of more people at the Mafia Wars Forum for Myspace/Facebook. Just go to the regular Mafia Wars page and in the top right corner, there is a link or thing saying about the Forums, click on there, sign up and you can get more mafia members.
Give me your mafia name and I'll send you about 30 of them.
You have to go to the inventory menu, click collections tab, -> mission collections. This will give you the option to ask mafia for help on the relevant mission that contains the calibration manual. when they find it (by doing a random mission over and over) you will get the piece. Alternatively, you can trade in one of the facebook mafia wars trade groups such as kingpin trading market or mafia wars trading club. (links attached)
Simply put, no. You can only take money out of your bank. I don't think you can rob someone in your own mafia either.
Clip the Irish Mob's Local Enforcer 9 energy required Soldier (lvls 9 - 12)

Go to the news feed that shows that you were attacked and mouse over the picture of your attacker. That will give you their facebook name - use the search function at the top right of your mafia wars screen to find that person (take note of their picture if they have a common second name e.g smith) and send them a friend request.
My basic Mafia Wars hints to playing the game: Play daily, give energy packs often, give gifts ( receive them too, never suggest 'trading' a gift unless it is rare), and be kind to your Mafia family members (and those not in your family also).
