Soldiers at the Mwanzaa Airport carry either Russian AK-47 rifles or Poly Tech Legend AK-47 Rifles. They are the classic AK design without the Chinese Type 56 Style hood.
A short AR15 full auto pistol (probably a Patriot Pistol) is seen being loaded by Kelly's men prior to the night battle and Dr. Karen Ross (Laura Linney) ends up using it during the fight. The pistol is built up from a Patriot barreled Upper receiver on a full auto Colt XM lower (possibly a Model 614 Export version), which has a partial magazine fence as opposed to the "slab side" receiver found on the SP1 Sporter. Rather than use the short buffer tube on most AR15 pistol variants, the armorers simply removed the XM177 style buttstock from the standard Carbine Buffer tube and kept it on the firearm. The finishes are noticeable different from the Patriot upper receiver and the Colt Lower receiver.

The buffer tube is simply the Colt Carbine buffer tube devoid of the buttstock and not the short buffer tubes provided on guns like the Patriot or other AR15 pistol variants.
Luger P08 handgun
A Luger P08 Handgun is carried and fired by Dr. Peter Elliot (Dylan Walsh).
I'm leaning towards a Winchester Model 70 without a scope due to the general shape. A background Kelly man holds a bolt action rifle but never fires it. Facing a horde of attacking Grey Gorillas one would want an assault rifle at the least.
Similar to the 'smart guns' used in the film Aliens, the camp has machine guns with dual drum magazines operating automatically to fire at movement 'out to 40 yards'. Though the Smartguns in the film 'Aliens' were actually German Spandau Machine guns, these are fake acetylene gas firing mockup guns.
