I want to know the answer to the following question:
What type of frag grenade is used by the U.S. Army?
All the background I'm provided with is that "The most common weapons used by the army are the compact variant of the M16 rifle, the M4 carbine, as well as the 7.62×51mm variant of the FN SCAR for Army Rangers.". Is that enough to answer the question?
Answer: no
