i spoke with anthony sheaffer about how the team in afghanistan could be shored up. are they going to have to shuttle guys in from other s.e.a.l. units? >> first off, they may have to degrade the mission in iraq and move more to afghanistan. the problem is things in iraq have not been as stable as people would like them to be. therefore, you're degrading that mission. the more likely scenario is they'll move one of the stand-by units and move them in ahead of schedule. >> but sheaffer and others say that carries significant risks in missions that are as dangerous as these. risks of mistakes and even possibly burnout, wolf. >> there's s.e.a.l. team 6. how many units are there? >> there's 2,500 s.e.a.l.s overa overall. even at full strength, this is a finite group of guys with a rot of stress. if they have to accelerate the deployment of now some who are in the rear coming up to the front, they could get burned out. it's a dangerous situation. >> our heart goes out to the families, the surviving family members of these s.e.a.l.s and the other u.s. troops killed in that
