This experiment compared the target detection and engagement performance of weapon-mounted off-bore systems using alternative visual displays for infantry soldiers in urban streets and inside buildings. Specifically, this trial compared the performance of soldiers using a weapon-mounted off-bore video sight in conjunction with a monocular occluded, see-through prism, and tablet display to the in-service C79 optical sight. A seven-day field trial was undertaken at the McKenna MOUT site at Fort Benning, Georgia over the period March 7 to March 16, 2003. Twenty-four volunteer regular force infantry soldiers from the Third Battalion of the Princess Patricia Canadian Light Infantry (3PPCLI) participated. The C79 in-service optical sight resulted in faster target detection times for both the Urban Streets and In-Building terrain when compared to the digital display conditions. During focus group discussions, participants commented that, while the Digital Video Sight (DVS) took longer for the target detection task, they were exposed less during the task and therefore felt that they were stealthier, achieved better surveillance, were able to detect threats around corners and inside rooms, and were able to zoom onto targets quickly, thereby improving their overall survivability. Although equally accurate and quick in detecting targets, subjective findings from the Urban Streets and In-Building terrain for the overall acceptance of the three digital display conditions showed that the p
