Front line

Leaders have often fought at the front lines either purposefully or due to a collapse in battle formation.

While a calculated risk, fighting on the front has in instances reduced communication and heightened morale.

These terms are used as battlespace control measures that designate the forward-most friendly maritime or land forces on the battlefield at a given point in time during an armed conflict.

[3] The attributive adjective version of the term front line (as in "our front-line personnel") describes materiel or personnel intended for or actively in forward use: at sea, on land or in the air: at the front line.

In the land campaigns of World War I, FEBAs, FLOTs and FLETs could often be identified by eye.
