Here you can find bitz and parts out of the previous Warhammer 40,000 Space Marine Tactical Squad box.
Each of these genetically upgraded fighters was formed by hard training and a rigorous selection process. They are the conscienceless weapon which is needed by the Empire to sow righteousness and to harvest obedience. On duty of the Emperor, they crush the unholy and spread his light, that his memory will endure forever. As long as the Space Marines bring the righteous will of the Emperor to all those who have strayed from his path, no heretic and blasphemer should expect mercy.
