The Bombard was a 29mm spigot mortar, weighing between 112 and 360 lb,  placed on top of a swivel or pivot.
It was able to fire a 20 lb high-explosive bomb to a range of approximately 100 yards; when the bomb detonated, it was able to inflict significant damage on a tank, although it was unlikely to actually pierce the vehicle's armour as the projectile was not able to gain sufficient velocity.
 It was served by a crew of between three and five men  The Bombard was considered to be most effective at short range, with targets being engaged with 'considerable success' at a range of between 75–100 yards.
It was a muzzle-loaded weapon and therefore had a slow rate of fire, averaging between six and twelve rounds per minute; as such it was considered vital that the weapon be well-camouflaged and that it hit the target with the first shot.
Two types of ammunition were provided for the weapon – a 20 lb anti-tank bomb and a lighter 14 lb anti-personnel bomb, with each weapon being issued with 150 rounds of the former and 100 of the latter.
The anti-tank rounds were found to
possess several problems.
They had insensitive fuzes, which meant that they would often pass through an unarmoured target without detonating, and when they did explode fragments were often thrown back at the crew.
 The Bombard was either affixed to a large cruciform platform, or an immobile concrete pedestal; in either case would usually be placed in range of defensive positions, such as road-blocks.
It seems that there was a preference for the Bombard to be used primarily in a static role, with extra mountings being built by the Royal Engineers to provide alternative positions from which the weapon could be fired.
In a static position, the weapon was usually emplaced in a pit with ammunition lockers nearby.
