Meaning :

In this army, there are heroes equal in military skills of Bhima & Arjuna like - Yuyudhana (Satyaki) and Virata and the Warrior Drupada; Dhristaketu, Chekitana & the courageous King of Kasi; Purujit, Kuntibhoja and Saibya, the best of men; Yudhamanyu, and courageous Uttamauja ; the Son of Subhadra - Abhimanyu & also the five sons of Draupadi - all of them being Maharathi's (Warriors).

Comment :

We can see the main Warriors in the Pandava army through this Shloka. Bhima & Arjuna were already regarded as the chiefs in Warfare but there are others equivalent to them in Pandava army, even though they are less in numbers. They are:

• Satyaki - Family member of Krishna and his teacher was Arjuna
• Virata - Father of Uttara, Arjuna's Daughter-in-Law. (Abhimanyu's Wife)
• Drupada - Father of the twins - Draupadi & Dhrstadyumna (From Yajna)
• Dhristaketu - Son of Shishupala & Dhristaketu's sister Karenumati married Nakula.
• Chekitana - Son of Dhirstaketu
• King of Kasi - Kashya
• Purujit - Son of Kuntibhoja
• Kuntibhoja - Father of Kunti, the Mother of Pandavas
• Saibya - Father of Devika, the wife of Yudhishtir
• Yudhamanyu - Son of Drupada
• Uttamauja - Another Son of Drupada
• Abhimanyu - Son of Arjuna from Subhadra
• Five Sons of Draupadi - Prativindhya, Sutasoma, Shrutakarma, Satanika, Shrutasena

Each of them were considered as Maharatha's - the Chief/Leader of an army with 11,000 soldiers. i.e, each of them have the powers equivalent to that of a Maharatha.

This shloka states that not only Dhrstadyumna is dangerous to Kauravas, but there are others also. Duryodhana is narrating the Powerful among Pandava's to Dronacharya.
