The M-16 will do the job, but they need to replace the gas pulse system with a gas piston system. The latter is more dirt-tolerant and more reliable than the gas pulse system now in place. And I agree with changing the calibers from 5.56 to 6.8 SPC, though I doubt the army will do that as the U.S. was the nation that pushed hardest for the 5.56 to become the NATO standard cartridge.

Its a joke - The 5.56 does fine. The fact that it fragments makes it particulary good considering its weight. Has high speed and long range as well. It explodes in the body with devastating effects at short range if fired from at least a 14.5"(No one understood why until about 1986), and at long range it will only wound (taking a medic and possibly one other person for a total of up to 3 off the battlefield to help the wounded, instead of only 1 person). It is the best round for the job in my opinion. If armor penetration is needed, an M955 (tungsten core) round exists and it will penetrate 12 mm of armor from a simple M-16. M855 will penetrate 6mm with its steel core.
6.8 would be nice, but then you run into the ammo carrying capability of the standard foot soldier again - bigger calibre means less ammo carried. I'm not sold on this round.
HK is pushing for the adoption of it's 4.5 mm, so maybe we haven't seen the end of calibre shrink yet. I'd think it would be a mistake to go to this round over the 5.56, but HK insists it has better armor penetration. Maybe so, but I doubt it fragments like the 5.56.

PS. I agree on using a gas piston.
