It is not 'psychological warfare', Aura.
It's a proven failure, that did nothing more than help VC recruitment drives. I can understand why Pete was a bit too close to the action, and is therefore in denial, but anyone who hasn't learnt from that failure by now shouldn't be on active service. It's not just bringing shame on their unit like Perry did, but it goes to helping the enemy. Take a look at yours, Vab's, and Pete's comments. They could go into any Al-Qaeda propaganda, without modification.
The only shame brought on any unit is largely the result of those who fabricate stories and accuse innocent soldiers like MCpl Perry.
BTW, why aren't you serving in the military?
