Description

The OQF 3.7-inch AA on Ram Mounting (QF 3.7 Ram) is a gift rank III British tank destroyer with a battle rating of 5.3 (AB/RB/SB). It was introduced during Update 1.95 "Northern Wind" in the Operation F.R.O.S.T. event. It features a heavily modified Ram chassis with a powerful 94 mm AA cannon, playing as a British counterpart of the German VFW and the two can often face each other in the battlefield.

General info

Survivability and armour

Armour

The QF 3.7 Ram consists of light armour composed of Rolled Homogeneous Armour (RHA) and structural steel.

Frontal armour of the Ram SPG, since Starfighters update, the 10mm armour is now 19.5mm.

The QF 3.7 Ram possesses light armour in the upper area of the turret (19.5 mm thickness), that might only cover your crew for small caliber machine guns.

Lying hidden in the back of the turret, its heavy 94 mm cannon is protected by 20 mm of structural steel located lower the cannon gun. Inside it the vertical aim drive is located. If a shot goes through and detonates inside this boxy structure, it will cause damage to your crew and the vertical aiming drive. This is the most common damage the QF 3.7 Ram will get, as the enemy often shoots at the area below the 94 mm cannon.

The thicker part of the armour is located in the cannon structure, visible in the centre of the turret (60 mm thickness). But due to the structural steel armour type, its armour remains insignificant for the heavy shells it can face, making cannon breech damage a routine situation as shells with explosive filler detonate within the structure

More armour is located in the lower central area of the transmission. There, the transmission mounting provides 50.8 mm of armour thickness, thick enough that it is possible to stop awkwardly angled shots or HE shots, but won't save you from a frontal encounter. Damages through here also will damage the transmission module.

Cannon structure armuor

Due to the QF 3.7 Ram's provided armour, any cannon shell sent its way can completely cripple your ability to retaliate. However, the QF 3.7 Ram's crew helps provide a factor in the vehicle's survivability on the battlefield.

The crew

The QF 3.7 Ram is managed by a 6 man crew.

• 1 Gunner
• 1 Loader
• 2 Machine gunners
• 1 Commander
• 1 Driver

The driver and a machine gunner remain in the safest spot within the vehicle chassis. The gunner it well placed but often gets knocked out. High crew skills are a must to ensure higher chance of resisting explosive effects or shrapnel, while performing gun reloads and field repairs even faster to fight back against the opponents.

The best way to utilize the armour to protect the crew is to aim the gun from the front, as it provides cover to both loaders in the back. However, avoid getting hit once as the proximity of the crew members, modules, and ammo racks within each other on the QF 3.7 Ram means a single hit has a chance of crippling the vehicle's performance enough for follow-up shots to finish the QF 3.7 Ram off.

Mobility

Game Mode	Max Speed (km/h)		Weight (tons)	Engine power (horsepower)		Power-to-weight ratio (hp/ton)
	Forward	Reverse		Stock	Upgraded	Stock	Upgraded
Arcade	44	6	29	568	763	19.59	26.31
Realistic	40	6		354	400	12.21	13.79

Mobility is decent for a SPG with such a gun, thanks to its light armour. 43 km/h in AB, 40 km/h in RB/SB.

The QF 3.7 Ram is able to reach its maximum speed of 40 km/h (RB) in off road terrain quite easily. Not enough to do a flanking manoeuvre, but enough to get a good sniping location or position early in the match.

Its reverse speed is quite poor, 5.7 km/h in AB and 5.2 km/h in RB/SB. However, this is enough for retreating from a sniping position effectively.

Close quarters should be avoided as it would just make the QF 3.7 Ram quickly spotted and flanked by enemy forces.

Armaments

Main armament

94 mm OQF Mk.II					Turret rotation speed (°/s)					Reloading rate (seconds)
Mode	Capacity	Vertical	Horizontal	Stabilizer	Stock	Upgraded	Full	Expert	Aced	Stock	Full	Expert	Aced
Arcade	44	-5°/+85°	±180°	N/A	9.7	13.4	16.3	18.0	19.2	7.8	7.4	6.3	6.0
Realistic					6.5	7.7	9.4	10.3	11.0

The 94 mm OQF Mk.II cannon provides very lethal penetration for all the enemy it faces. It's different from any other cannon in the British tree until battle rating 5.0, as this cannon holds a lower muzzle velocity than your usual 17-pdr gun. Therefore some practice should be made to familiarize with the new cannon ballistics.

Usage in battles

In Realistic/Simulator battles, the best approach is the sniping role. Quickly find an appropriate spot at the beginning of the match. The vehicle is tall and the gun depression is only of -5° so keep that in mind when positioning. Covering the allies flanks, long roads, taking down enemy snipers, or keeping the enemy from capturing a point shall be your duty.

A good tactic is to wait enemies expose their sides. Tiger and Panther tanks don't have the armour to resist the 94 mm cannon, and so one shot will usually be enough. The 44 shells it can carry is sufficient for prolonged sniper duties. The same can be said of Soviet vehicles, as their frontal armour tends to ricochet rounds, so it's recommended to aim at the sides as well. As enemies pass by, wait for the right moment to shoot, but make sure to correctly range the targets and lead the gun to successfully land the first shot.

This tactic can be more successful with camouflage on the frontal armour. Concealing the QF 3.7 Ram in the woods as well as hiding the exposed loaders in the back from easy picking.

Shooting the enemies frontal armour is possible, but the risk of shots bouncing off is still high, despite the gun's penetration capabilities. This will also expose the QF 3.7 Ram's position, which will lead enemies to pour down machine gun fire, artillery, and aerial strikes to suppress and eliminate the QF 3.7 Ram.

Pros and cons

Pros:

• Powerful 94 mm gun capable of penetrating most enemies it faces from the front
• Gun can fully traverse at 360°
• Due to the large size of the gun it can reliably one shot other vehicles due to its immense spalling capabilities, even sometimes from the side, unlike most British tanks
• Decent survivability due to 6 crew members, the 2 members inside the tank being the most covered
• Due to its large size, shells may sometimes pass right through without causing too much damage, with thin enough armour that APHE shell fuses sometimes won't trigger at all
• Good mobility and fast gun traverse for its powerful gun, allows some aggressive-defensive playstyle in close quarters
• Not a common vehicle, you might confuse the more inexperienced players to the point they may not know where to shoot
• Amazing reload speed, even more when crew is trained or aced
• Elevation of +80°
• Good top speed

Cons:

• Has no timed fuse shells for aircraft, unlike its German counterparts
• Weak armour and exposed crew, SPAA and strafing aircraft can quickly shred it apart and is only partially protected against light machine guns, even from the front
• Longer reload compared to its German counterpart, the VFW
• Poor gun depression of -5°
• Lower muzzle velocity than the usual 17pdr, learning and quick correction is needed.
• Ammo racks are stored at the very side of the tracks, experienced players will know to shoot at it, even High Explosive shells can set them off
• Artillery can often knock out several crew members at once, even from a distance
• Has hull break, like most open top vehicles

History

In 1941, General Frederick 'Frank' Worthington, founder of the Canadian Armoured Corps, proposed that a 3.7 inch anti-aircraft gun be mounted on a Ram chassis to act as a mobile anti-tank gun. The OQF MK II was the primary British heavy AA guns during World War II. The Canadians used this gun for experimenting, mounting it on the Ram chassis. Few examples were made and one was sent to Great Britain for trials, but no further development came of it.
