120mm mortars are 'fine' and doing a good job - out to a range of 4,000-5,000 metres.

And re. numbers of artillery pieces:

120mm mortars are 'fine' and doing a good job - out to a range of 4,000-5,000 metres. They lack the range to hit Russian units in their assembly areas, 10km (+) behind the frontline, though: where every single shell could kill lots of enemy.

And re. numbers of artillery pieces:

- 300 = enough to, finally, and definitely, stop the Russians;

- 500 = enough to start pushing them back (not for a clear-cut victory, though).
