Say it with a flash! TFB’s Photo Of The Day is on a mission to collect high-quality photos from the world of firearms, and what’s better than a meter-long muzzle flash? Above you see Tech. Sgt. Jason Cangemi, an armorer for the 103rd Rescue Squadron, 106th Rescue Wing as he test fires an M4 carbine during a multi-day training course at the firing range on April 9, 2015.

While the muzzle flash here seems impressive, under real-world tactical conditions it would likely be extremely muted through the use of a supressor. The live-fire training consisted of multiple events, including tactical movement, responding to incoming fire, retrieving and caring for wounded individuals and night-time shooting.
