This study was undertaken to determine if the US Army's M119 Howitzer could be safely towed in the 'firing' position using the existing A-Frame brace to support the gun tube during movement. A computer model of the howitzer was developed that would predict motions of the howitzer and consequently. loads . on critical components. The results obtained from this computer model were validated by comparing them to actual data obtained from an instrumented test done on the howitzer at Aberdeen Proving Grounds, Md. The validated model was used to predict the 'worst case loads on the howitzer's A-Frame and the T-Bar during movement in the firing' position. The maximum predicted stresses in the A-Frame and the T-Bar from the 'worst case' loads were compared to the yield stress. These comparisons showed that the A-Frame and T-Bar were strong enough to withstand the 'worst case' predicted loads that would be caused by towing the M119 Howitzer in the 'firing' position
