I suggest deleting the whole ActivatesWhenReleased line for every grenade. Its broken badly last time I checked. Also impact explosive are very risky and have a high risk of blowing up in your hands (especially when moving and throwing at the same time), so it'd be safer to make it a timed grenade.

The Howitzer is far superior the field gun. You see, since the Howitzer not only reloads a bit faster (I think), and the charge is the same, it can easily be used for defense. The field gun has to be put in the line of fire because of it's range. An explosive launcher can either be a lobber or rocket propelled, and since it isn't either, it's more difficult to use. The howitzer, on the other hand, is most definitely a lobber. With a lobber, and some simple logic and aiming skillz, you can be a marksmen with what is essentially a big grenade launcher.
The charge in these shells aren't too strong, but they aren't strong enough. It isn't underpowered, nor overpowered, and it certainly ain't balanced. The actual particles emitted by the shell are very powerful, and the clusters can blow out brains, but what you need are the air particles that are usually in the bombs we see. These particles don't rape terrain, but they send out a nice shock wave that can rape face if the fraggy bits don't get to them first. These air particles have to be insanely high in numbers to work well, but that's acceptable.

If you don't know, I'm pretty sure it's the Uber Cannon sprite/weapon attached to a Howitzer body.

This mod is going to take you places Kettenkrad!
it is awesome that you are fixing the Stielhandgranata and i was wondering if the submarines are still active???
Huntsman (to those who understand)

Correct my friend, 1 question, when is 1.4 out????

Later, I wan't to get the U-Boat to work. ACrabs sink in the Hydro mod. It'll have to be an AHuman, but that'll be wierd, cause it will be able to... Hold weapons and bombs and stuff .
Unless I 'dunno, what if I put AEmitters on the bottom to stop it from sinking...

You can either:
A) Modify the Hydro mod to not ignore crabs (it did not anticipate this situation, so the script could definetely be improved. You can PM akblabla to change it).
B) Make it an Actor (not ACrab or Ahuman) and have the weapon be run entirely through Lua script. It might be even better, since the torpedo goes straight so it wont need additional aiming.

One problem: I'm no sparkle magic wizard. (Also, can you give Actors limbs, and would the script respond to me pressing the movement buttons if it is an Actor?)
However I was thinking: What if the U-Boat could be bought from the menu as a null AHuman, then (with some crazy .lua h@x) gib itself (therefore dropping any guns / bombs). The sub would have an AimRange of 0 or what ever, and the torpedoes would have a homing script. It would have a preset inventory of the null torpedo gun. I guess then you can still drop the weapon though.

And the tanks are too small.
