Unjust Deception of the Enemy?

While I was reading the New York Times online this morning, an article came up in my feed that really interested me. The topic was about usage of booby-trapped weapons during warfare; particularly within the conflict in Syria.

For more background information and current usages, please read the article here. 

I find this topic extremely intriguing. Within the article, the downsides to the usage of bobby-trapped weapons (such as bullets, mortars and hand grenades) were many, but I truly think this is an effective way of fighting an enemy. 

Case of Bullets (NYTimes.com)

One of the ways of distributing such rigged weapons (bullets especially) are to intentionally push a crate off of the back of a supply truck, hoping that the enemy will see the newly found crate as a mistake made and free ammunition for their own use. This method however, has downsides. Not every bullet can be booby-trapped, because otherwise, the enemy will stop it's usage. Therefore, a select few of the bullets are actually booby-trapped with a TNT like substance, rigged to blow up upon firing. 

Vietnamese Soldiers (NYTimes.com)

The United States actually used exploding ammunition long before this conflict in Syria. In the 1960's, the United States leaked exploding ammunition to the Vietnamese soldiers, causing mass casualties, but effectively destroying weaponry of the Vietnamese in the meantime. 

Personally, I think that this is an incredibly valid form of warfare, although the legality of it is still unknown. If physically killing someone on the battlefield is completely legal in warfare, I take a strong stance of support about this topic of purposely placing explosive ammunition and other forms of weaponry in locations which the enemy will most likely find and use. 

What's your opinion on this topic? Should this form of warfare be allowed? Please let me know!
