Russian 107mmMTR range 10 to 152
American 107mm MTR range 14 to 100
British 107mm MTR range 24 to 98

Both the Russian and the British mortar have maximum elevation of 80 degrees.

I ask because I was reading an account of a battle where British 4.2 inch mortars were involved and the ranges involved were 500m to 600m (ie 14 hexes)
Any ideas?
