== Description ==

The '''{{Specs|name}}''' is a premium rank {{Specs|rank}} British light tank {{Battle-rating}}. It was introduced in [[Update "Regia Marina"]].

This is your standard in-tree [[Crusader II]], with a historical camo. This tank was called the Saint and served with 10th Royal Hussars regiment, which was part of the 2nd Armoured Brigade, 1st Armoured Division, which fought in the North African Campaign.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

Armour protection on the Crusader "The Saint" is the same as the [[Crusader II]], and as a cruiser tank is understandably poor in most areas. The hull is generally very penetrable, only averaging 30-40 mm of equivalent protection. However, the two protrusions for the driver and machine gunner have hatches which can easily block a shot or in some cases reduce spalling, only knocking out 1-2 crew with APCBC. Side and back armour are predictably weak.

The turret armour is the thickest on the cheeks, and the angled sides can also block or bounce rounds if correctly angled and baited. The mantlet is a clear weakspot, often resulting in the turret crew being completely wiped out. The armour on the tank is supplemented by the 5 crew members, which can save players from a one-shot. In the case of the mantlet, the three turret crew may be knocked out, but the tank will survive if the driver and machine gunner remain, allowing those positioned away from the enemy a chance to get away. Additionally, the gun, coaxial machine gun, and optics in the mantlet can also block shots, though this shouldn't be relied on.

== Usage in battles ==


'''Simulator:'''

The I-15 can be used in turnfighting, bomber intercepting and ground pounding. Like in AB and RB, it is excellent in turning tightly and continuously, and it has lovely low-speed handling and low stall speeds (unlike its successor I-16), making it a great starter plane for sim. However it does have its drawbacks: the rather big nose blocks the visibility a lot, offering very poor over-the-nose visibility which is a disadvantage in a turn fight, because when leading a shot the enemy will always get obstructed by the engine, making the player guess the shot. Also its upper wings will get in the way when you look aside. Plus, it has an awful telescope-like gunsight, so when zoomed in the I-15's nimbleness is magnified, making the aim super wobbly. You cannot see anything around which greatly reduces your situational awareness.

Note: it is recommended to set the convergence within 300 m, with vertical convergence on, because the majority of turnfights happen at that range or closer.

Note 2: in a turnfight you must get used to shooting without zooming in, as you really can't see anything with its awkward scope when zoomed it. However when tailing a straight-flying plane that scope doesn't seem that bad

Before engaging a fight, it is better to have an altitude advantage first. When approaching the fight try to figure out which is your teammate and which is the enemy, to avoid going for a second pass, as the energy retention of the I-15 is rather slow. Also pick your target carefully. For easier aiming, you want to go for those unmanoeuvrable twin engine aircraft like [[Ju 88 (Family)|Ju 88]] or [[Ki-45 (Family)|Ki-45]], or bombers if there are any. Given the bad forward visibility of the I-15, these are the best options as they are quite slow and sluggish, and are a bigger target to hit. However getting hits on them doesn't mean good damage, so you must be patient. When dealing with fighters, it is way harder to aim. The elevator control of the I-15 is extremely sensitive, giving it good manoeuvrability, but at the same time, bad handling. The I-15 will respond in a very fast turn upon moving your stick/mouse by a little bit, which makes tracking nimble planes quite hard. But once you get used to it, try to lure every enemy into a turnfight, as that is where the I-15 shines. Quite a bit of bullets are required to effectively damage the enemy so you must be patient. If you find an enemy at your 6, utilise your great roll rate to do defensive manoeuvres like scissors to make them overshoot. Or you can simply do tight turns, most monoplanes won't be able to cut inside your turn and they might disengage.

If you are not very experienced in sim, you can also go for even bigger targets (bombers) for easier aiming. However you want to be more careful when hunting bombers, since with the Sim control (whether it be mouse joystick or a real stick) the plane will manoeuvre much more gently, making itself a great target for the bomber's gunners. DO NOT follow behind a bomber's 6 unless you are sure that its tail gunners are unconscious. Chasing behind a bomber makes yourself stationary for the tail gunners, and you will be showered with bullets. Your big radial engine will usually get damaged. Instead, before attacking, get an altitude advantage over the bomber by flying around 2 km above it. The bomber should only fill up about 1/6 of your gunsight. The best position for an attack is at the bomber's high 6 so you can adjust the lead much easier. Dive at the bomber, but not directly at it, try to predict where you two will crash by imagining yourself as a missile, that's where you should aim at (deflection shooting). To maximise the damage it is better to aim for their wings and engines, as the fuselage usually soaks up quite some bullets. Only fire when the bomber passes in front of your guns. This short window might seem inadequate to do anything, but with a accurate burst on the engine the 4 MG can at least damage it. With an engine damaged most bombers cannot go far.

Ground pounding ability is average as there are only few bombs and rockets. The 6 rockets, with accurate aiming, can destroy 3 targets, whether them be tanks or pillboxes. The small 50kg bombs can be used on light pillboxes. Once the suspended armaments are gone, the 4 MG are good for killing soft targets like trucks, artillery and AA cars.

'''Enemies worth noting:'''

[[Ki-27 otsu|Ki-27]], [[N1K1]], [[He 51 (Family)|He 51]], [[Gladiator (Family)|Gladiator]], etc:

Those commonly seen planes are equally good at turnfights and will be a hard target to down since they are very small and agile. To deal with them you need to practice leading and deflection shots, plus manoeuvres like barrel rolls and scissors. They still need plenty of bullets to get damaged, so these kind of targets are the hardest to kill and requires great skills from the player.

[[Do 17 Z-2|Do 17 Z]]:

This early twin engine plane always shows up as an AI controlled reconnaissance aircraft that you have to down, which is a good news as AI won't manoeuvre aggressively. However this plane is extremely durable for the I-15's weak MGs. When it shows up as an AI, deflection shots are not recommended as the small shooting windows really does nothing. Instead, try disabling its 2 gunners first, then just sit behind it and burst on its wings and engines. When attacking the gunners try to not get your engine damaged by pulling evasive manoeuvres as soon as the bullets come close, since the Do 17 can outrun the I-15 in a level flight.

=== Pros and cons ===


'''Pros:'''

* Extreme turning abilities: one of the best turn-fighters in-game, able to turn tightly and continuously with other biplanes
* Firepower is rich with 4 x 7.62 mm MG, moderate damage and plenty of ammo
* Good rate of climb
* Small silhouette meaning you are harder to hit
* 2 x 50 kg bombs allow you to have ''some'' ground-pounding abilities in ground battles
* Fixed gear is convenient for quick landings and takeoffs
* Very short take off distance
* Low stall speed, beginner friendly to land and manoeuvre
* Open cockpit allows you to easily hear nearby aircraft in Simulator
* Nose-mounted MGs means no need to worry about convergence distances

'''Cons:'''

* Very slow speed: cannot keep up with early monoplane fighters (eg [[He 112 (Family)|He 112]]) or even some bombers such as [[Do 17 E-1]]
* Will quickly lose speed gathered in a dive
* Average roll rate
* Open cockpit can usually get the pilot sniped
* Small 50 kg bombs require very accurate aiming
* Telescopic gunsight offers very limiting field of view in Simulator
* Big engine blocks the visibility over the nose, a disadvantage in a turnfight in Simulator
* Side views are obstructed by the upper wings and supporting structures
* Very wobbly with Simulator controls, making it hard to aim precisely
* Vulnerable to heavy machine gun fire (eg. [[Browning M2 (12.7 mm)|.50 cal M2 Browning]], [[Breda-SAFAT (12.7 mm)|12.7 mm Breda-SAFAT]])

== History ==


On the 7th July 1937, fighting broke out between Chinese and Japanese forces, starting the Second Sino-Japanese War. When the war began the Chinese air force was using many obsolete aircraft, such as the [[Hawk III]], which were no match for the Japanese A5M fighters.<ref name="PolikarpovAces">Maslov and Postlethwaite 2013</ref> China rapidly signed the Sino-Soviet Non-Aggression Pact with the USSR, and as part of the agreement the Soviets began Operation Zet to secretly supply China with aircraft and pilots.

Between October 1937 and September 1939 the USSR delivered 885 aircraft (rising to 1,250 by 1941) to China, including 215 Polikarpov I-15 aircraft delivered very soon after the deal was agreed (eventually rising to 347 I-15s). At first the Soviet pilots would have to fly the aircraft over 1,500 miles across China to get them to their destination of Lanzhou, however this was a risky journey and so future batches of aircraft would be disassembled and transported to Hami (closer to Lanzhou), before final assembly and delivery to Lanzhou.<ref name="PolikarpovAces" /> The Soviets also sent 250 volunteer pilots to fly the I-15s for China. The fist I-15s were delivered in November 1937. In Chinese service the I-16 became known as the "Chizh" or "Siskin".<ref name="PolikarpovAces" />

A number Chinese aces flew the I-15bis; among them Liu Chi-Sheng who achieved 6 of his 10 kills while flying the I-15bis.<ref name="ChinaAces">Cheung and Davey 2015</ref>
