I dug deep into research!
The Egyptians used the soviet SKS model 1943 rifle and a copy of the Carl Gustaf m/45 smg in the conflict. At least two hundred T-34, SU-100 and IS-3 tanks.
-The 6th infantry brigade was still using British equipment! Staghound armored cars, land rovers and jeeps mentioned. British 25 pounder artillery (88mm), Archer self propelled anti tank guns and 57mm towed anti tank guns.
Even though Egypt had concluded a major arms deal with the Soviets in September 1955, the Egyptian 6th Brigade still possessed mainly British World War II-vintage weapons and vehicles, but it had no tanks. This forced the Egyptian commander at Abu Ageila to rely on antitank weapons and artillery firepower against Israeli armored attacks. The 3d Artillery Regiment contained sixteen to eighteen British 25-pounders (howitzers with 88-mm cannons possessing a range of up to 12,000 meters). The 78th and 94th Antitank Batteries each consisted of eleven self-propelled Archers, a total of twenty-two. The Archer, first adopted by Britain in 1942, mounted a 76-mm antitank gun on a Valentine tank chassis. The antitank gun faced backwards, which reduced its effectiveness in attacks or counterattacks. Boulos had the Archers from the 78th Antitank Battery and elements from the 94th Antitank Battery entrenched in the forward positions at Umm Qatef and overlooking Qusaymah Track, leaving him with only eight Archers in the second echelon. The Egyptians also had approximately three dozen towed 57-mm antitank guns that were organic to the infantry battalions. To deal with the Israeli Air Force, the 6th Brigade had an antiaircraft battery of 30-mm guns. The main combat vehicles available to the Egyptians were Staghound armored cars, normally armed with 37-mm guns, and Bren carriers, lightly armored vehicles.
The British were still using the Sten Mk V smg.
Syrians had just gotten some 45 Panzer IV and 12 Panzer III spg (Stug?) earlier that year!

Israeli forces: French 6 by 6 trucks, M-4 Shermans, AMX13 tanks. 105-mm recoilless antitank guns.
Colonel Uri Ben-Ari, perhaps Israel's premier tanker in 1956, commanded the 7th Armored Brigade, which had two tank battalions, the 9th and the 82d; two battalions of infantry, one mechanized (52d), the other motorized (61st); a reconnaissance company; and a battalion each of 120-mm mortars and 25-pounders (see figure 2). The 9th Armored Battalion consisted of AMX13s-light French tanks weighing 14.5 tons, mounting a 75-mm gun, and having a speed of thirty-five mph. The 82d Armored Battalion, on the other hand, had the Israeli Sherman M-4s, with either 75-mm guns from the AMX-13 tanks or 76.2-mm guns. The Sherman tank weighed thirty tons and could travel up to twenty-five mph.
This will be further edited as a bored Gunsalot continues to google stuff while at work...
