The Rules says every fire weapon has its minimum range. But I coldn't find any information about its maximum range.

Obviously the maximum range for close combat weapons and for heavy weapon won't be the same!

Please help to solve a question...

maximum ranges are immaterial due to the close combat ranges of the Tannhauser maps

I believe Tannhauser ops addresses this question

If it doesn't say use infinite max range unless that makes no sense.

And think about the grenades...

OK - I'll try again

The maximum range of all 'ranged' weapons is farther than any distance that can be found on a standard Tannhauser map.

This includes grenades

as long as you're on the path it can target any circle that's not occupied.
