Crysis help

[Grovyle]

Hi

I have got Crysis yesterday, and I am stuck in the second mission...

It says to I destroy 2 tanks, but I have no clue how to destroy them without a rocket launcher or something..

Help plz?

In the houses there are some rocket launchers located with some other ammonation.

When your inside that kinda school building, go to the lowest lvl of the building.
Then there is a little room where a rocket launcher is, tanks take about 2 to 3 shots.

Ok, i passed the tank part,

But I need help again...

I have found Prophet, near a cave entrance blocked with loads of rocks...

How do I take those rocks out?

p.s.: If i need a rocket launcher... I fail I don't have any rocket ammu now

You don't need to shoot 'em. I just jumped to that cave.
