The Frag Grenade is the standard grenade in the 40k universe.
If it explodes it catapults dozens of razorsharp shrapnels which cut through armour and flesh. 
  
The Bolt Pistol is the little brother of the Bolter.
It has a decreased range, less rate of fire but the same penetration power. 

The Bolter is most commonly used by Space Marines as their standard armament since the Great Crusade.
It fires an explosive tipped projectile called a bolt and is one of the deadliest weapons in mankinds arsenal. 

The Space Marine light-scout workhorse, the Yangrel-pattern Combat Motor-Bike is capable of putting out a quick speed of over 60 KPH off-road while remaining well armoured.
Mounted on its fore-shield, is a coaxial pair of .75 calibre Bolters fed with an internal non-discintigrating link feed.
It is capable of a slightly slower rate of fire compared to the heavier storm-bolter.
