The paper attempts to study the ideology in selected extracts from Chris Kyle's American Sniper (2013). A critical stylistic analysis is used to realize the objective of this research. The writer presents his experience as an American sniper during his military service after the American invasion of Iraq in 2003. The aim is to examine the way of describing parts of Iraqi and American societies and study samples of their individual members and investigate the conceptual meaning of the components of the nominal groups (henceforth NGs) to reveal the hidden ideology. One of the ten tools from Jeffries' approach (2010) which is naming and describing is used. The denotative and connotative meanings of the components of NGs are examined. They have either positive or negative connotations. The results expose ideology and the political, social, and psychological impact of such description on the American readership.
