jackson was a sniper the us did have an official role for snipers in ww though it was a different one than the current more fieldcraft based version that you are thinking of note the scene where caparzo gets shot jackson points out the church and says that's where i would be and sets up for a sniper kill on the target because he does have a knowledge of sniper tactics jackson is clearly a sniper rather than a dedicated marksman a role that did not exist in ww swatjester son of the defender
