True, and it will be a help. But, as I'm sure you know, there is a lot more to being successful in the military sense than mastering video games. One also needs the development of teamwork, dedication of self to the mission, courage, thorough military training and personal stamina - among a long list of other requirements.

"Vicious" and "relentless" do not a successful warrior class make, although these can be plusses when controlled in a disciplined way. Besides, while insensitivity may make one vicious and destructive, it fails to follow it will make one either relentless or a warrior in a military sense. A coward or bully may also be "vicious" and "relentless" and these people are not generally successful soldiers when the chips are down. Why? Because they are always looking out for #1 and not what needs to be done!

Again, this may be true when everything is going their way. But, when the technology and battle is not going their way it will take other qualities to turn it around and prevail.
