I think you should be able to salute! Like.. type "salute" in the Console and ur guy will do a Salute Animation! I know its kinda pointless, but I'd like to see it implemented
Stand at attention, stand at ease, present rifle, rocket chill (resting RPG launcher against his leg). EDIT: I already have that on SecondLife.
why not have this display whenever the "roger" radio message is sent? Similar animations could be done for the others also. "Can I join your squad?" could be polishing the squad leader's boots lol. Nice idea, but not a priority.
