 Today we're doing block 3 and 4 PTP for our OEF deployment for 14-1, so we're basically going over roll 1 care, roll 2 care, that's a non-surgical and surgical resuscitation. Well for our training we have some subject matter experts that came down from Belbo, Kent Benelton, a couple guys with MLG, and we also have a training 3T which has a simulation training, so these guys are getting, you know, near life experience taking care of these guys, so a lot of these mannequins that we're using, they bleed out, they have heart rates you can adjust, and they have an algorithm, so based on their intervention the parameters of the patient's vital signs and stuff will adjust on that. So the STP, STP is roll 1 care, so that's where we do non-surgical intervention or non-surgical resuscitation, and the roll 2 is where we do surgical resuscitation, and that's the key of where our simulation training is. It's good training for the sailors and the OR techs and nurses because we, because certain don't work alone, they work as a team, so the sooner that we can get these guys working together as a team and are more cohesive, then they'll be able to take care of patients better in theater.
