True, but the situation continues to evolve. The widespread distribution of 7.62mm rifles and MGs down to section level (helped by the fact that the British have just joined the US in selecting the 7.62mm Minimi) has to a large degree addressed the range and (to some extent) the effectiveness issues of 5.56mm, but has created a new problem - ammo weight!

I see they've also joined the US switch to Multi-Cam uniforms. Adopted a new helmet, too.

I presume they shoot standard NATO ball ammo in the L129A1 rifle? Do you know what muzzle velocity is from that 16" barrel? Maybe 2600 fps?
