The table lists armour penetration values for armi anticarro della fanteria britannici as well as cannoni britannici da 0 al 100 metri range e 0 degrees inclination of armour. Dates indicate the year when a particular shell type entered production, not necessarily the year of availability to combat units. New shell types would take several months to reach the troops at the front, some favoured units receiving the new shells more quickly than others. Andrew Mark Reid is the author of Panzergranate, a set of regolamenti di wargame using prudentamente researched gunnery data to simulate armour penetration results.

| Grenade No 68 |
H.E.A.T. (Munroe) | 89 mm |
| The No 68 was based on a Swiss idea to use the well documented Munroe effect for armour penetration. The No. 68 had a shaped charge con 5.5 ounces of explosive. |
| Grenade, Hand, Anti-Tank No 74 |
Chemical (Thermide) | 42 mm |
| The Sticky Bomb was rejected by the Army in the U.K. as being too dangerous for use by troops so it was issued to the Home Guard instead. Anyone who has seen the film Dad’s Army may recall that the main hazard was the Bomb’s ability to stick to the user’s trousers, which then gave the user 7 seconds in which to remove his trousers, e remove himself to a safe distance. |
| P.I.A.T. | H.E.A.T. (Munroe) | 85 mm |
| The P.I.A.T. (proiettore anticarro per fanteria) britannico was different from Bazooka e Panzerschreck rocket projectors, Panzerfaust e RPG, in that it developed no backblast. The weapon had a spring operated firing mechanism which actually hurled the bomb instead of using a propellant to fire it. The P.I.A.T. could be fired safely from a building o similar enclosure, ed it would not betray its firing position as easily as the Panzerfaust. If the P.I.A.T. misfired, the spring could be difficult to re-cock manually. |

| Cannone contraerei/anticarro da 20 mm L.65 Breda |
A.P. | 36 mm |
| L.R.D.G. e S.A.S. raiders britannici used captured Italian Breda cannons to arm veicoli. |
| 20 mm L.72.4 Polsten (Centurion Mk.I) |
A.P./T. | 40 mm |
| 20 mm L.85 Hispano (Hurricane Ftr.) |
A.P. | 47 mm |
| 20 mm L.110 Oerlikon 1 Pdr. |
A.P. & A.P./T. | 62 mm |
| The cannone anticarro Oerlikon 1 Pdr. was mounted on leaf sprung tracks in servizio britannico in order to be towed behind Carden Loyd T.9 trasporto cingolato e Mk.I Universal carriers. The weapon was withdrawn from active duty in 1938 when the 2 Pdr. became available. It was again issued to some Home Guard units during 1940 in preperation for the German invasion that never came. It also served as a anti-tank gunnery range trainer throughout the war. The weapon had no shield fitted. |
| 25 mm L.77 Hotchkiss Anti-tank Gun |
A.P. | 54 mm |
| A cannone anticarro francese used by the BEF in Francia e Norway. Many were left behind at Dunkirk. The weapon offered less armour penetration than the 20 mm Oerlikon, ed it was taken out of service when ammunition supplies ran out. |
| 2.8 cm schwere Panzerbüchse 41 |
A.P.S.V./A.P.S.B. | 94 mm |
| L.R.D.G. e S.A.S. raiders britannici are known to have used captured Panzerbüchse cannoni anticarro tedeschi to arm some of their veicoli. |
| 40 mm L.52. 2 Pdr. |
A.P./T. | 84 mm |
| 40 mm L.52. 2 Pdr. con Little John |
A.P.S.V. (1943) | 103 mm |
| The Little John squeeze bore attachment was designed to increase the velocity ed armour penetration of the 2 Pdr gun. It was introduced when the 2 Pdr was already obsolete. Autoblindi e carri armati leggeri which could not be upgraded to a larger gun, received the Little John attachment to keep them in service a while longer. When the 6th Airborne Armoured Recce Regiment landed in Francia in 1944 most of their gliderborne carri armati Tetrach were equipped con Little Johns. |
| Cannone contraerei da 40 mm L.60 Bofors (1933) |
A.P. & A.P./T. | 100 mm |
| 40 mm L.70 Bofors Flak |
A.P. & A.P./T. | 117 mm |
| 47 mm L.23. 3 Pdr. |
A.P.H.E. (1928) | 27 mm |
| A.P./T. (1937) | 40 mm |
| The 47 mm L.23. 3 Pdr. was the main armament of the Vickers 6 Tonner B. tank which served con the Bolivian army during the Chacos war in 1933, and, in limited numbers, con the Chinese army during the invasione giapponese. The Finnish Army deployed the 6 Tonner during the 1938 Winter War con Russia, but the entire unit seems to have been knocked out o destroyed in their first attack. Recovered veicoli were converted to self-propelled guns, mounting the 127 mm howitzer britannico in an improvised torretta. These veicoli were used in the indirect fire support role, ed as direct fire assault guns. Several of them survived the war, ed are in Finnish museums
now. |
| 47 mm L.31. 3 Pdr. |
A.P.H.E. (1928) | 36 mm |
| A.P./T. (1937) | 54 mm |
| 47 mm L.41. 3 Pdr. |
A.P.H.E. (1928) | 48 mm |
| A.P./T. (1937) | 72 mm |
| The 47 mm L.41. 3 Pdr. was a towed cannone anticarro which was
replaced in frontline use by the 2 Pdr. gun. However, the 3 Pdr. remained in service in
1940 for home invasion defence, e there is footage showing the weapon on maneuvers.
I affusti of the cannoni anticarro 2 Pdr. e 3 Pdr. were similar in appearance. |
| 57 mm L.23. 6 Pdr. |
A.P.H.E. (1916) | 32 mm |
| 57 mm L.45. 6 Pdr. (Tank Gun) |
A.P./T. (1941) | 84 mm |
| A.P.C.B.C. (1943) | 106 mm |
| The cannone da carro et cannone anticarro 6 Pdr. listed below did not have H.E. shells issued for them. This meant that these guns could not be used for close defence against fanteria o provide fire support during assaults. Why this was, nobody knows, but there are accounts of anti-tank gun crews britannici making their own case shells for close defence against fanteria assault. This was done by removing the A.P. shell head, filling the cartridge con a suitable piece of cloth, filling the shell case con stones e gravel, e sealing it con another piece of cloth o encasing the shrapnel content in thick axle grease. This tactic was quickly improvised in the North African campaign, e there is some indication that carristi employed it con the 6 Pdr. L.45 as well. |
| 57 mm L.50. 6 Pdr. (Anti-Tank Gun) |
A.P./T. (1941) | 94 mm |
| A.P.C.B.C. (1942) | 118 mm |
| 75 mm L.40. 10 Pdr. (Tank Gun) |
A.P./T. (1943) | 115 mm |
| A.P.C.B.C. (1944) | 124 mm |
| The 10 pdr. cannone da carro was an adaptation of the cannone anticarro 6 pdr., designed to fire the ammunition of the US M3 75 mm gun. It was mounted in Churchill e A.27M Cromwell tanks. |
| 75 mm L.56 Flak |
A.P./T. | 140 mm |
| 76.2 mm L.58. 17 Pdr. (A.T. & T.G.) |
A.P./T. (1943) | 146 mm |
| A.P.C.B.C. (1943) | 179 mm |
| A.P.D.S. (1945) | 253 mm |
| 77 mm L.50. 17 Pdr. (Comet Tank Gun) |

| A.P.D.S. (1945) | 218 mm |
| 84 mm L.64. 20 Pdr. (Centurion Mk.II) |
A.P.C.B.C. (1946) | 217 mm |
| A.P.D.S. (1946) | 307 mm |
| 88 mm L.28.8. 25 Pdr. (A.T. & F.G.) |
A.P./T. (1939) | 94 mm |
| 94 mm L.18. 18 Pdr. (Field Gun) |
A.P.H.E. (1916) | 42 mm |
| A.P. (1931) | 62 mm |
| The 18 Pdr was mounted in A.13.C.S. (Close Support) versions of the Christee cruiser tank. There were also a few carri armati Crusader built to this specification for a similar purpose. The 18 Pdr. field gun was used in the direct anti-tank fire role during a battle in defence of Singapore. It is recorded that carri armati leggeri Tipo 95 giapponesi were successfully defeated by these guns using armour piercing shells during an attempt to rush a defensive position. The 18 Pdr. was the
only anti-tank weapon available at the time. |
| 94 mm L.50. 3.7 Inch Flak |
A.P.H.E. (1933) | 117 mm |
| A.P./T. (1944) | 194 mm |
Many of the guns e carri armati built in the 1920s e 1930s were employed in Abyssinia (Ethiopia), some even served in the front line defences of Tobruk, North Africa. Carri armati Vickers 1928 from General Hobart’s pre-war outpost army were dug in to provide static anti-tank defenses there. Their 47 mm L.40. 3 pdr. guns proved inadequate against carri tedeschi, but they could still knock out the lightly armoured carri armati italiani.
