-The Vulcan M61 sight has incorrect modelled. That is a giro stabilised lead computing sight with independent movement on vertical (has separate from the vulcan cannon by a sigh mount), not properly simulated TM-9-2350-300-20-1 (page 2-203, 2-294, 2-303, 2-350, 2-359). The lateral movement permit at a internal sight, move on rotation 300 mils left and right with help of the firing computer). The internal sight can cage and uncage by the gunner. TM-9-2350-300-20-1 (page 1-9)

- The Vulcan fire control has 5 fire modes (Radar, Local, Ground, External and test).

-- Radar mode has the normal mode in use, except the radar has inoperative or jammed. Radar determine the necessary data to impact in the target (not a floating sight as actually has modelled), the gunner maintain the target centred on the M61 sight and the fire computer make the appropriate corrections on elevation and lateral correction.

-- Local mode use the sight and the data introduced by the gunner as to calculate the impact point

-- Ground mode use to attack ground targets

-- External mode has use with external personal to insert fire distance and open fire.

-- Test has use to testing systems.

Fire modes has explained on FM 44-5 (page 4-1 to 4-8 and 5-1 to 5-7) and TM-9-2350-300-20-1 (pages 1-24 to 1-25)

 

- The M168 20mm cannon, has 2 fire velocity modes. Low rate (1000 rpm) and High rate (3000 rpm). Hight rate has 10, 30, 60 and 100 selected burst. TM-9-2350-300-20-1 (page 1-20)

- Two Sight, a M134 straight x6 Telescope and a M56 night vision x7 sight has mising on the vulcan for ground attack. FM 44-5 (page 1-2 and 5-2) and TM-9-2350-300-20-1 (pages 1-24 to 1-25)

 

-The Vulcan have a Ammo Drum with 1100 20mm ammo bullets ready to action, the Vulcan vehicle carry 1000-1500 ammo bullets on a ammunition stowed into the vehicle to recharge the Ammo Drum (time 100 bullets by minute, 11 minutes full reload). The empty ammo drum and ammo holder can reload if the vehicle has next to a truck with ammo recharges.

-The Vulcan AN/VPS-2 radar has a minimum range of 250 meters and maximum range of 5000 meters (with a 1 square metre target), has connected push a foot switch.
