A person who is very enthusiastic in military activities and expert in releasing different kinds of weapons is called heroic.
Regarding Krsna's heroism in fighting, there is the following statement: "My dear killer of the enemy, just as the elephant while taking bath in the lake destroys all the lotus stems within the water by swinging its trunk, so simply by moving Your arms, which are compared to the trunks of elephants, You have killed so many lotus-like enemies."
Regarding Krsna's expertise in releasing weapons, when Jarasandha and thirteen divisions of soldiers, attacked Krsna's army, they were unable to hurt even one soldier on the side of Krsna. This was due to Krsna's expert military training. This is unique in the history of military art.
