Characteristics:
’Mech pilots earning the BloodName Sennet are the foundation of the warrior caste. They are recognized throughout the Clan by their strong dedication, proficient tactical awareness, and unequaled desire for victory. They consider a sense of trust among fellow MechWarriors invaluable to the team. They are strong proponents of honor and justice among Clan society; in the current timeline of Clan Diamond Shark, three Sennets have held the OathMaster's office.
Sennets excel in leadership situations. They constantly labor to better understand modern ’mech warfare and know when to exploit a situation. They appreciate fellow warriors who understand the need to improve. They are always available to others who may need assistance, and one of the most identifying characteristics of Sennets is their continual testing of one another’s skills.
Sennets are trained to utilize every technical and environmental advantage on the battlefield. They are taught that their Mech is just one element at their disposal. Not accustomed to fighting from behind cover using Long Range Missiles or artillery, Sennets exhibit and preach fluidity in combat. They are comfortable riding the heat curve with energy weapons as well as utilizing fast moving close-range autocannon platforms. Their preferred tonnage class ranges from mediums to heavies, but they always request the most tactically important mechs available for an offensive, regardless of size.
