Tank Grunt wants to be just like his old man. He spends his days lifting heavy things, dodging imaginary bullets, and being bigger than the other guy, but deep down inside, he wonders if anyone really knows who he is.
Tank Grunt (later known as Colonel Tank Grunt) is the oldest son of General Buzz and Lyla Grunt. He is the older brother of Ripp and Buck, but he is distant from both of them. Tank is the only one of his siblings who wants to follow their father into the Militarycareer and the only teen in Strangetown who doesn't have any friends when the neighborhood is first played. Tank's name is a reference to his military background and heritage.
Tank wants to follow in his father's footsteps and aspires to become a General like him. They have a good relationship, but Tank wants to impress him by getting a Military job. Tank is also part of the feud against the Smith family. He is enemies with Johnny Smith and wants to win a fight against him. If Johnny throws a party while still a teen, Tank will attempt to crash it.
When first played, he is 5 days away from becoming an adult. Either the Grunt household or the computer itself is scripted so that whenever Tank searches for a job, the first result will always be the military career track.
He considers his father, General Buzz, a friend, though the friendship is not mutual. This sort of one sided relationship would not have been possible without the use of hacks such as SimPE.
Surprisingly, Tank doesn't have any bodyskill points or indeed any skill points at the start of the game. He has exactly the same interests as his father. According to his Sim DNA in SimPE, he has recessive alleles for blond hair and grey eyes.
Strangely, when looking in his family album, Tank appeared to have lighter skin as a child in one of the photos, while his father Buzz had darker skin. Tank also had lighter skin in another photo as a teen.
Life leading up to The Sims 2 (PSP)
Colonel Tank Grunt lives in the Barracks at the military base Division 47 with General Buzz, Corporal Ripp and the Smith family. His youngest brother Buck doesn't appear in this game. Someone has hacked Tank's computer and the player's Sim has to repair it. During this time, he will constantly attack Ripp until his computer is fixed. It is also possible to sell secrets to Tank, but the one he wants to know is why Mister Smith is outside around midnight, snooping by the alien crash site. If you choose not to tell him, he will become very angry with your Sim.
Oddly, Tank's eye colour in the PSP version is brown, but in the PC game, his eyes are blue. This is also the case with his brother, Ripp. Both of them are adults in this game.
