[i]Hanging Gardens of Babylon: 

While within the fortress, all of Semiramis' parameters are increased in rank, her fame level is also boosted to the highest class, and [u]attacks are revised in her favor.[/u][/i]

Of course, Semiramis did not want some alien grenade exploding within her garden. As inconsequential as the damage would be and as infinitely replacable these guards were, she still did not want this alien... thing blemeshing her garden. As such, the "attack" of a grenade was revised in Semiramis's favour. What revision would favor her? if Lasberbreak had mistimed the tossing of the grenade and had brought it with him, armed, through the green portal. 

3... 2...

The grenade was now in Laserbreak's hands and the portal was closed. Have fun with that, Decepticons.
