tank more tank weapons grenade rocket artillery

[siniox]

TL;DR

The tank has many weapons. It still needs more. Give it a grenade launcher and a rocket launcher. (and maybe an artillery weapon upon researching artillery? with massive recoil and/or starcraft-like siege mode?) (completely serious about this last one)

What ?

everything is in the TL;DR
edit:i just remembered discharge defence exists. Give it to the tank, too.

Why ?

The tank needs love. The tank needs weapons. All the weapons the game already has (except laser because we already have personal laser defence).
