The AIT program has several divisions involved.  These divisions include:

A.I.T. [Alternative Incapacitation Tactics]
A.I.T. 2 [Alternative Incapacitation Tactics Level 2]
H.R.E.S [High Risk Entry Support]
In order to protect our material and avoid unauthorized personnel from acquiring the AIT materials knowledge, the curriculum is not published in written form.  However a couple videos are included to show you what is possible.

Alternative Incapacitation Tactics 

Alternative Incapacitation Tactics 2

Along side of alternative incapacitation tactics level 2 also includes learning how to withstand a blow to the body.  Many can withstand this to their body but the groin and neck are also included.
