In this video I demonstratie a little glitch in Call of Duty: Modern Warfare 2. With a Javelin and a Semtex grenade equipped you can create a huge direct Martyrdom.

STEPS:

1) Equip a Javelin and Semtex grenade
2) Switch to your Javelin (wait until the weapons is fully loaded)
3) While your Javelin is active, throw a Semtex but hold the RB (X360) or R2 (PS3) button
4) While holding the RB / R2 button, switch back to your Javelin by pressing Y (X360) or triangle (PS3)
5) Walk into the enemy and wait for them to kill you

6) BOOOOOOOM! (less info)
