I am a 744 driver and have been into all the big US bases in Afghanistan. Our company procedures is a standard NADP-1 departure profile. There is no "tactical" departure in a 744 except maybe to turn early but everyone does the same thing. Personally I try to keep it at 250 or whatever we need operationally all the way through FL 180 before accelerating just to get above the service ceiling of the more expensive MANPADS but most of the bad guys don't have that kind of $$$.
