All of the 101st Airborne soldiers in the film carry XM16-E1 rifles, the interim variant of the M16 rifle which combined the 3 prong flash hider with the A1 style upper receiver. In reality, the 101st AB, at this stage of the war, did NOT carry the XM16-E1, but had the M16A1 with birdcage flash hider, a fact pointed out by Hamburger Hill Veterans when the film was released.
Soldiers in the beginning of the film have ModelGun Corp replica MGC M16s slung to their backs as they load wounded onto helicopters. One of the giveaways is the 'blued' 20 round magazine (the real 20 round magazine is anodyzed aluminum), the shape of the pistol grip and the rear sling swivel. The most obvious detail is not seen here, the fake forward assist of the replica rifle.

Chinese Type 56 Assault Rifle
Other than the milled receiver AK-47s (which are probably Poly-Technology Legend series rifles), there are obvious stamped receiver Type 56 style AK rifles with underfolder spike bayonets (aka "PigSticker". This variant has a stamped receiver, the version in the film has a milled receiver.)
The Chinese variant of the Russian SKS, the Type 56 Carbine with spike bayonet, is used by the NVA combatants in the film.

This is particularly hard to see due to the heavy rainfall and dense smoke of the scene. The front sight is flipped up, most likely occurring when the rifle snags on debris as the man crawls back and forth from his hole. The sight cannot be used in this manner for any sort of aimed fire, so he is purely pointing and shooting.Error creating thumbnail: File missingNVA soldier with a Type 56 Carbine (SKS) fires next to an NVA using a Type 56 Assault Rifle (AK47) - 7.62x39mm
M79 grenade launcher
Used by McDaniel (Don James) and then later by Pvt. Joe Beletsky (Tim Quill)
A variety of 'lemon grenades' are seen on soldier's web gear throughout the film. They are often seen from a distance on webbing or in men's hands as they are thrown. In real life they are supposed to be M61 Grenades (virtually identical to the M26A1 lemon grenades most associated with Vietnam), however, these have a slightly unusual shape, implying that they are some sort of 'trainer' grenade that is not often used to impersonate the M26/M61 series of grenades.
When Sgt. Frantz (Dylan McDermott) is lecturing the new members of the platoon, he uses a former NVA crossover (a participant in the Chieu_Hoi program [1]) named "Han" to demonstrate how 'not paying attention' will get them killed. Han is 'armed' with a long empty tube made to resemble an RPG launcher of sorts. It has a dud Warhead on it. "Han" demonstrates his skill and ability by avoiding the noisemakers, trip wire and barbed wire of the perimeter to get within striking distance of the G.I.s
Throughout the film, the enemy uses the Chinese Type 56 (aka Type I) stick grenade. It is an oval pineapple style grenade on a short wooden stick and noticeably shorter than the famous German Stielhandgranate of WW2 fame.
Seen in the distance on some of the perimeter shots of the base camps and mounted on M113 APCs.

Contrary to what is depicted in the film, soldiers riding vehicles were supposed to wear their M55 or M68 flak jackets, even though they were not bullet proof, they protected against grenade or bomb fragments, including roadside mines and boobytraps. Only in close quarters battle where quick movement trumped ballistic protection, did the soldiers ditch their flak vests.
M1911A1
M72A1 LAW Rocket
Carried by some soldiers, but not seen used. Since the enemy at this stage had no armor to defeat, the M72 LAW rockets were used primarily as 'bunker busters', though they are not effective against soft earth targets like the tunnel entrances on Hill 937.
Error creating thumbnail: File missingAn M41 Walker Bulldog tank with an 76mm M32 Main gun is seen in a field during a lull in the fighting. The fact that this tank has U.S. Armored Division markings is a bit of an anachronism, since the M41 was only supplied to the ARVN and was an obsolete tank for U.S. Forces. In fact, the M41 was perfect for the ARVN Armored units, since it's interior was too small for "American" tank crews but perfect sized for the small statured Vietnamese tankers. The Bulldog's secondary armament was one Browning M2HB .50 Cal machine gun and an .30 Cal Machine gun
