As a 22 year Army veteran, I become almost nauseous viewing war movies with numerous technical errors. The "Marine" assault battalion fires a 3.5" rocket launcher from a moving train without regard to the back blast effect on the Marines riding directly behind the weapon.
The army uniforms were hokey. Army officers, under the rank of general, have two insignias per lapel, a "U.S." and a branch insignia. About half the time one of our heroes has his worn correctly, the other half of the time incorrectly.
The rescuing Marines have corpsmen with them that have ludicrous looking helmet liners with huge red crosses on them. Those crosses would have made great targets for even a blind sniper.
The soldiers accompanying the train were geared up for combat wearing their helmet liners sans helmets. They also were wearing an American flag patch on their left shoulders. These flag patches should have been on their right shoulders (I know D-Day invasion forces had these flags sewn on, but I am not too sure about our soldiers in Africa) and their unit patches on their left.
Certainly wish some of the directors/producers could spring a few bucks and hire some ex-GI's as technical advisers.
