The heavy mortar is integral part of the heayv fire support of any bataillion, bringing a far heavier bomb to the enemy then the smaller light mortars. Due to their weight (45.2 kg can't be lugged around by foot, not even by Selkie), other transportation is needed: While transport via horse is possible, trucks or APCs are preferred.
