Combat Hero Grenade

When you're in those trenches fighting for your life behind enemy lines with no hope of reinforcements and are quickly running out of bullets you don't just lie down, give up, and die! You're an action hero for goodness sake! You're the modern warrior we've all come to idolize! You've been in worse situations than this. Now let's check the surroundings. You've got a bunch of enemies coming at you from the warehouse and there's some sort of truck right next to them carrying what looks like rockets. A bullet couldn't pierce them but if you had something to cause the initial explosion you just might be able to cause a chain reaction! Wait a minute! You have your last grenade at your hip. Now to just lob it the inhuman distance from here to the grenade sized hole in the tarp on top of the truck that you can't even see from down in the trench and cause an explosion that would never realistically reach all the enemies but somehow defies physics and totally does in the coolest way possible. You've got this!
