embusquer

Literally to place in ambush or lie in wait (embusquer des soldats), and reflexively (s'embusquer), to hide or take cover — the root of the well-known World War I term un embusqué, someone who used connections to dodge front-line combat.

• Les soldats se sont embusqués derrière la colline. — The soldiers took up ambush positions behind the hill.
• Le tireur s'était embusqué dans un immeuble abandonné. — The gunman had holed up in an abandoned building.
• Ils ont embusqué une patrouille ennemie à l'aube. — They ambushed an enemy patrol at dawn.

Mostly a military/tactical verb — a learner is more likely to encounter its derived noun un embusqué (WWI slang for a draft-dodger) than the plain verb in everyday conversation.

• expression Embusqué — World War I French army slang (from embusquer) for a man who used connections or a rear-echelon post to avoid front-line combat — contrasted with un poilu, the frontline soldier.
