Either you two harass me, or you are 1) ignorant of the way Q3 weapons are positioned

There once was a Strogg guard who disobeyed orders from his (tank) commanders. He rebelled and ended up doing three things: a) fabricating a new right hand, releasing him from a low status on the job market, b) training and working out till he got beefier and able to jump and c) torturing prisoners of war after the Earth attack on Stroggos. The Vadrigar got wind of the latter and rewarded this guard's efforts with a place in the arena. Voila.

After the assassination of the Makron, the Strogg realized they underestimated the human capability to adapt. They realized they had relied too much on mechanical discipline and raw firepower, their utter technological dominance which had been their primary strength was now their primary liability. As a result, they formulated a new and simple plan - give their troops more brains to go with their brawn. This guard was the first of a new breed of soldier, a prototype that was superior to the original prosthetic-weapon guards. Smarter, faster, tougher, and able to adapt and use the enemy's weapons against them. Well, all first attempts tend to be flawed, and by their loosening of their reigns on the mind he regained too much self-awareness. His conscious will clashed with his Strogg programming, turning him psychotic as a result, and he began slaughtering anyone and anything he could find. This made him perfect combat material for the Arenas Eternal, and so prior to being evaporated by a supertank's rocket barrage, was claimed by the Vadrigar for eternal combat. Eventually the Strogg overcame these flaws and developed the best balance of combat smarts and technological control over their ranks just in time to give their forces an edge against the invading Marine landing. These are the new Strogg seen in Quake 4.
