Raja Todarmal was an acclaimed warrior, leading the Mughal forces to several resounding victories, the most notable of which was the conquest of Bengal from Afghans. He was a char Hazari (mansabdar of 4000), second-highest rank. Raja Todarmal's son Dhara was also a skilled warrior who laid his life down in an expedition to Tattha. The other Khatri commanders in the Mughal service at the time included: Rai Parmanamd, Pitamber Das, Rai Kesho Das, Rai Mathura Das.

In Shahjahan's reign, Raja Manik Chand Khatri was appointed as the Governor of United Katehar to protect it from warring chiefs. He was succeeded to the position by his son Raja Makrand Rai.
In the Mughal rule, we find mention of a large number of Khatri military generals and provincial governors, from Kabul to Deccan. It is not possible to mention all. Even during the reign of Siraj-ud-daulah, one of the main commanders for Subah-E-Bangal was Rai Durlabh (Mahindra Khatri)
The house of Jaipur received services of acclaimed Khatri soldiers and warriors like Raja Aya Mal, Raja Harsahai, Raja Gursahai, Raja Nand Ram, and Raja Narain Das Khatri. A book written by Rajputs themselves, call Raja Narain Das “bravest of the brave”
Guru Hargobind (a Sodhi Khatri himself) was trained by a Khatri warrior Bhai Ganga Sehgal. In Guru Gobind Singh's first war, most of his main companions were Khatris. This includes Guru's cousin Sango Shah and his four brothers, some Sodhi's, Mahant Kirpal Das (Khatri)

In 1718, Kirtichand Rai, the Khatri Raja of Burdwan, subjugated the Raja of Bishnupur in a full-throttle military expedition and increased his own domains greatly.

From the very first War in 1947 to Kargil there has been no conflict or war in India that did not witness the gallantry of the Punjabi Kshatriyas (Khatris).
