Yeni Ordu bünyesinde her biri 100 kişilik 12 taburdan oluşan 1 alay ağır süvari gücü bulunuyordu. Albay John Okey komutasındaki birliğin muharebedeki temel görevi piyade keskin nişancılarını öncelikli olarak bertaraf etmekti. Devriye ve keşif görevlerinde de kullanılan birlik kuşatmalarda arkebüz ve el bombalarıyla açılan gediklerden girişi zorlardı. [[Forlorn hope]] birliklerini çoğunlukla bu birlikler oluştururdu.

The New Model Army contained one regiment of dragoons, of twelve companies each of one hundred men, under Colonel John Okey. Dragoons were mounted infantry, and wore much the same uniform as musketeers although they probably wore stout cloth gaiters to protect the legs while riding. They were armed with flintlock "snaphaunces" rather than the matchlock muskets carried by the infantry.
On the battlefield, their major function was to clear enemy musketeers from in front of their main position. At the Battle of Naseby, they were used to outflank enemy cavalry.
They were also useful in patrolling and scouting. In sieges, they were often used to assault breaches carrying flintlock carbines and grenades. The storming party were sometimes offered cash payments, as this was a very risky job. Once the forlorn hope established a foothold in the enemy position, the infantry followed them with their more cumbersome pikes and matchlock muskets.
In 1650, Okey's dragoons were converted into a regiment of horse. It appears that after that date, unregimented companies of dragoons raised from the Militia and other sources were attached to the regiments of horse and foot as required. This was the case at the Battle of Dunbar on 3 September 1650.[8]
