American "might" cockiness.... are we really that "mighty?"
We got our @sses handed to us in Vietnam by peasants with weaker weaponry. While we cleaned house in Iraq twice, we're losing badly to roving guerilla terrorists. We position our soldiers in the line of fire and lose pubic morale when we start filling body bags senselessly. Didn't we learn anything from the Revolutionary War...? We may as well put "redcoats" on our soldiers and give them loud drums to play whilst they march in formation into enemy lines! How does this relate to a battle rifle?
I think many underestimate the NEED for a superior battle rifle. Let's not forget that world allies and enemies can form overnight and it only takes one leadership change and a few years, or a major world event to sever allegences and form allies. WWII is a great history lesson. Shortly after losing WWI, the tiny country of Germany was on the brink of world domination mainly due to surprise and superior weaponry and equipment. While we were "allied" with Russia during WWII, we quickly became bitter enemies with the superpower. World allegencies and enemies can change overnight.
Today's world is as ever evolving and there are serious threats looming over the Free worlds' heads, and the Free world (NATO) can't even agree on who the bad guys are! The world is watching the US limited success (some would say failure) in the Middle East, and the dissention among the ranks back in America; enough public pressure and you bet the US will pull a Vietnam. Meanwhile, China and India, both superpowers, are engaging in massive oil grabs in the Middle East to feed their ever growing economies and industrial growth. China in particular has a very powerful military might and won't hestitate flexing its muscles, and other nations could soon ally with China, including N. Korea. Something of a world war over resources (i.e. oil) with these oil starved nations is not out of the question. China in particular frightens me because they are an organized, well funded, superpower that won't crumble under public sentiment like the United States often does.
Imagine a head-to-head war with China. While the logistics are unlikely because neither will invade the other, they will take 100,000 casualties without flinching and continue fighting without hesitation, yet the US flinches with 1,000 casualties. A head to head fight with China would crush the United States because they have more troops, their troops are fanatics (like the Japs in WWII), and their government is supremely in charge. Contrast that with the US who flinches and wants to pull out prematurely of an operation that is largely successful with few (historically speaking) casualties.
There are REAL threats out there. The M16 may be fine for the weaker armies like the Iraqis, who were poorly trained, malnurished, and frankly unmotivated once it was clear that they would lose. However, if we ever get into a fight with the big kid on the other block, we'll be happy we really invested some R&D into a quality battle rifle.
I echo the sentiments of others above that both like the Bullpup and like the M16 platforms.
However, all things equal, if I have the choice of gun that has a longer barrel in an equivalent sized package (or a shorter gun with the same length barrel), that is also lighter in weight (eg the 'pup), I'll take the pup. Lord knows the M16 was far from perfect when put into battle, and significantly worse than the gun it replaced until it was corrected. And, that design STILL has deficiencies. Given some imagination and R&D $, the deficiencies of the 'pup can be corrected as mentioned above with little thought investment. To address the common problems:
1. Use caseless ammo to reduce weight. Cased ammo can eject downward.
2. Ballistic and noise barriers in the chamber to protect against noise and kabooms
3. Practice quicker reloads -- not a deciding issue as any skill can be learned
4. Bayonets is not a deciding issue either. Due to the reduced weight of the rifle (and caseless ammo), I would carry an extra 30 round mag over a bayonett if given the choice. I see the bayonet as having limited application in modern warfare. I think if you're down to using the bayonet, your time is limited. Besides, a smaller and lighter rifle may actually be easier to wield as a weapon with a bayonet.
Also, this discussion cannot be complete without a nod to needing a better cartridge. IMO the 5.56 is underpowered in many respects, but the 7.62 is probably overkill. Develop an intermediate cartridge, like the 6.5mm. Also, why NOT have ONE rifle that can fire two different lenghts of the same bullet for different applications. Make a 6.5 short and 6.5 long for urban or desert settings.
