Faisal Shahzad, the suspect in the failed plot to bomb New York City's Times Square, has told U.S. investigators that he received bomb-making training at a camp in Pakistan's Waziristan region. Given the botched, even amateurish nature of Shahzad's attempt -- he forgot to take the keys to his getaway car, for instance -- many observers are now asking: What exactly does one learn at a terrorist training camp?

First of all, today's terrorist training camps are not what they used to be. Sprawling al Qaeda camps complete with such amenities as firing ranges, like Tarnak Farms near Kandahar, Afghanistan, where Osama bin Laden is believed to have plotted the 9/11 attacks, are largely a thing of the past.

Today, al Qaeda outsources most of its training to Pakistani outfits like Tehrik-e-Taliban Pakistan (TTP) and Lashkar-e-Taiba (LET), the group believed to be behind the 2008 Mumbai attacks. The camps these groups run are often small, just one or two buildings, and temporary -- such groups stay on the move to avoid detection by satellite or intelligence agents. These groups are believed to be increasingly sharing resources when it comes to training. According to some estimates, there are about 40 militant training camps around Pakistan.

Enrolling in a militant training program is not easy, particularly for foreigners. Groups like the TTP, whose leadership has been decimated by U.S. drone strikes in recent months, are extremely wary of outsiders, believing that anyone who turns up looking for training could be a spy.

Five young American men learned this the hard way last December when they were picked up by Pakistani authorities after being rejected by several militant groups. However, wannabe jihadists of Pakistani descent, like Shahzad, can improve their odds of enrolling by having a relative or friend vouch for them. Insurgent groups with Western connections, like the so-called "German Taliban," are also believed to vet potential recruits from abroad.

Assuming you meet the entrance requirements -- Pakistani security officials say camps train only about 20 recruits at a time -- the curriculum can vary.

A typical day will begin with morning prayers, followed by a sermon on the significance of jihad. Physical drills and operational training take place during the day. Instructors are typically veteran jihadists, although in groups like LET or the Kashmiri nationalist organization Jaish-e-Mohammed, former members of Pakistan's intelligence services are also believed to have been on the
