It was armed with 1 light machine gun. Its main armament consisted
The Light Tank MkIV was a development of the Carden Lloyd machine gun carrier. This version was similar to the MkII but had a longer superstructure to the rear.
The front engined Meadows 88hp engine drove the tracks under the four coil sprung Horstman suspension road wheels, past the rear idler and back over the single return roller.
The turret was angular and contained the Vickers .303 machine gun. | |

About Penetration Figures
All penetration figures in this database are calculated to a common standard
based on German WWII testing criteria (complete penetration with functioning fuze).
This allows direct comparison between all nations' guns.
Original national test figures would be higher for some nations due to different criteria:
- German: 1.00? (baseline - strictest)
- British: 1.02? (slightly looser)
- American: 1.05? (50% mass through plate)
- Soviet: 1.10? (75% mass through plate)
For example, a Soviet gun showing 159mm here would be published as ~175mm in Soviet documents,
and a German gun showing 120mm would be published as 120mm in German documents.
The 159mm figure is directly comparable to the German 120mm - the Soviet gun really was more powerful.
|
| National Testing Standards |
|---|
| German: | 1.00? - Complete penetration, fuze functions (strictest) |
| British: | 1.02? - Complete penetration |
| American: | 1.05? - 50% of shell mass through plate |
| Soviet: | 1.10? - 75% of shell mass through plate |
|
All database figures are normalized to German standard for direct comparison.
Multiply by the factor above to see original national test figures.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.
The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive
and numerous books and websites that have provided the detailed information that has not been available anywhere else. The
information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre,
the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation
originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
