Tank, Cruiser, Mk VI Crusader (A15)

Although the Crusader was faster than any tanks it opposed, its potential was limited by a relatively light 2-pounder gun, thin armour and mechanical problems. A particular tactical limitation was the lack of an High Explosive (HE) shell for the main armament - these existed but were never supplied. Axis tank forces developed an extremely effective tactic of engaging British Imperial tank forces by retiring behind a screen of concealed anti-tank (AT) guns. The pursuing tanks could then be engaged by the artillery. With the German anti-tank guns out of range of the tanks' machine guns and without a high explosive shell to return fire, the tanks were left with the equally unpalatable options of either withdrawing under fire or trying to overrun the gun screen.

After the completion of the North African Campaign, the availability of better tanks such as the Sherman and Cromwell relegated the Crusader to secondary duties such as anti-aircraft mounts or gun tractors. In these roles it served for the remainder of the war.

INSTRUCTIONS FOR USE

Rez the chassis item on the ground.
Now simply ride the vehicle portion while selecting wear for the hull (Attaches by default to the pelvis)
You have two forward gears (PG UP and PG DN) as well as reverse.
Click anywhere on the hull to fire the main gun. To fire the machine guns, click on the rounded end of the smaller gun.

/3 lightsoff

I am discounting this item because it's an old fashioned SL vehicle with a rezzable base and wearable prim details.
