Combat use
![BL6inch30cwtHowitzerOnSiegeCarriageDiagram](https://upload.wikimedia.org/wikipedia/commons/5/58/BL6inch30cwtHowitzerOnSiegeCarriageDiagram.jpg)
This gun was designed as a siege howitzer firing a special howitzer shell. It was designed to be fired from a static siege platform, with wheels removed, for accurate long-range shooting. When fired mounted on its normal wheeled travelling carriage, which had become standard practice for modern medium artillery, its range and accuracy diminished due to limited elevation and also lack of a modern recoil mechanism.

as part of the British siege train. It was during this campaign that the short range limitation became evident, and shell weight was traded for greater range in 1901 with the introduction of a "light" shell which increased maximum range when firing from its wheeled travelling carriage to 7000 yards. No use was found for the siege platform which allowed elevation to 70°: ”This capability was designed for distinct siege operation, and in South Africa the need for this did not arise. In this theatre the platform was an encumbrance, and it was discovered that it could be dispensed with.”

When World War I began approximately 80 guns were still available. They constituted the only true heavy artillery the British army possessed, and were heavily engaged in the early battles in France and Flanders. It was adapted to use the standard gun shell, with a slight enlargement of the chamber to produce Mk I*, allowing slightly larger propellant charges. It served in all theatres, including the Western Front, until replaced by the modern 6 inch 26 cwt howitzer from late 1915. At

, where there was a lower priority for modern ordnance, the 6 inch 30 cwt was used at Helles by 14th Siege Battery RGA (4 guns), attached to 29th Division, and at Anzac by the

, the Howitzer Regiment dispatched a 155 mm ''(sic)'' Howitzer Squadron from 1919 to early 1922, which was used as Army Reserve Artillery. After February 1922, the Howitzer Regiment was fully deployed in Asia Minor, but its 9 batteries were being mainly used to reinforce divisional artillery in the front sectors that were deemed dangerous for a turkish breakthrough.
The BL 6-inch 30 cwt howitzer continued to serve in the Greek Artillery for another 18 years, but from 1932 it was already rendered "obsolete" and in need of "extensive repairs to return to operational status". Despite this, at least 16 pieces were deployed behind the "
