| Notes | The 15 Lang 15 was a British 6in howitzer that was bought by the Dutch in 1920. The howitzers were designed by Vickers and served during world war one. The Dutch modernised them by adding tyres for better traction on roads. They were issued to artillery regiments at corps level and saw action in 1940. |
