The arrival of the Su-34 'Fullback' fighter bomber to Syria could be seen as imminent since the initial deployment of the first combat assets to Syria, and has now finally confirmed to have occurred in recent days. Up to six Su-34s are now believed to have joined the four Su-30SMs, twelve Su-24M(2)s and twelve Su-25s already present at Hmeemeem/Bassel al-Assad IAP, Lattakia Governorate.

With Russian military support to the Syrian government having been brought to an entirely new level in the past month and international media focussed on the influx of aircraft and armoured vehicles to Syria, little has yet been uncovered about the extent of new small arms deliveries to the regime. However, the Russian Vesti state-owned news channel aired footage of Syrian soldiers equipped with British-made Accuracy International Arctic Warfare Magnum (AWM) sniper rifles on the 27th of September, revealing a wider procurement policy than previously thought.

After the sighting of Su-30MS' and Su-24M2s over Syrian airspace just days ago, new satellite imagery acquired by Stratfor and AllSource Analysis dating from the 20th of September has now revealed the presence of twelve Su-25 'Frogfoots' being assembled at Hmeemeem/Bassel al-Assad IAP for a total of twenty Russian combat aircraft now confirmed to be deployed in Syria. Around the same time, U.S. officials claimed that no less than twenty-eight combat aircraft and up to twenty helicopters have now been stationed in Syria as part of wider Russian deployment of military personnel in Syria.

Amid a range of reports of sightings of Russian military personnel and equipment used in combat in Syria, Russia's role in the conflict escalated sharply with the confirmation of Russian aircraft and armoured vehicles being flown in by the dozens. Coinciding with the renovation of Hmeemeem/Bassel al-Assad IAP for use as a Russian military base, Il-76 strategic airlifters or (more likely) Il-78 aerial refuelling planes have been sighted escorting military aircraft such as the Su-30SM and Su-24M(2) over Syria, together with An-124 strategic airlifters reportedly carrying at least two Mi-17 and two Mi-24/35 helicopters amongst a range of other weaponry.

This list only includes vehicles and equipment in service with the Yemeni Army before the Houthi takeover of Yemen in 2014 and 2015. Vehicles and equipment acquired and produced during the ongoing conflict are not included in this list. The goal of this list is to comprehensively catalogue the pre-war inventory of the Yemeni Army, list the country's esoteric AFV designs as well as clarify what military equipment is currently available to Yemeni parties on the battlefield. Civilian trucks towing military trailers are not included in the list.

The regime's offensive in the Lattakia Governorate continues to reveal previously unknown details about Russia's involvement in the Syrian Civil War. Apart from the sighting of recently delivered Russian BTR-82A infantry fighting vehicles (IFVs), new evidence now confirms Russian military personnel has a key role in leading the offensive on the ground.

The vehicle-borne improvised explosive device (VBIED) has been made famous by the fighters of the Islamic State in Syria and Iraq over the past two years. One could even argue the Islamic State perfected the concept by constantly building and deploying better protected and even larger variants on the battlefields of Syria and Iraq. From using radio-controlled toy cars to even tanks and self-propelled artillery to carry explosives, the Islamic State has done it all.

Recently published images of two drones that fell near the village of Ruveysli near Kasab and Arafit near Jisr al-Shughour in Syria's Lattakia Governorate on the 20th of July 2015 reveal that either Russia has supplied the regime with state-of-the-art unmanned aerial vehicles (UAVs) or that Russia has embarked on a small-scale drone surveillance programme over Syria. If the latter turns out to be the case, it could be part of their greater intelligence programme to provide the Syrian regime with up-to-date information on the rebels' status and strength, which first became known to the world after the capture of the Центр С - المركز س - Center S SIGINT (Signals Intelligence) facility near al-Hara, Daraa Governorate.

Iraq's war on the Islamic State has seen a myriad of both light and heavy weaponry from all sources around the world in use with the numerous groups pitting it out against the Islamic State in Iraq. From Iranian tanks and multiple rocket launchers to World War II-era howitzers, the war in Iraq has so far provided it all.

The Syrian Civil War has presented itself as a perfect opportunity for nations to test their newest weaponry in an unforgiving combat environment, and this large influence of modern weaponry has seen everything from assault rifles to laser-guided bombs and drones undergoing their combat debut. Nonetheless, it has also seen the return of weapons once presumed to have found their final resting place, but which are now brought out to fight once more.

The Saudi-led airstrikes which commenced late on the 25th of March on Yemen reportedly hit a large number of targets throughout the country, yet mainly focussed on the single S-125, three S-75 and two 2K12 SAM sites around the capital of Sana'a. Also hit early on was the airbase of al-Dailami, which shares the runway with the adjacent Sana'a International Airport.

Following local experiments with spaced and slat armour on T-72AVs and BMP-2s, the 4th Armoured Division initiated a small-scale upgrade programme for its armour in the summer of 2014. After upgrading several of its T-72M1s and bulldozers with additional armour, the 4th Armoured Division is now also operating at least one ZSU-23-4 self-propelled anti-aircraft gun (SPAAG) upgraded in the same fashion.

To everyone's surprise, the Syrian Arab Air Force (SyAAF) has been able to maintain a high pace of operations in the now almost four-year long war. Orginally destined to engage in a fierce but short war with Israel, it never anticipated to fight what is essentially a war of attrition between the regime and its adversaries, and has found its role in the conflict through trial and error. The SyAAF saw a large part of its aircraft and helicopters upgraded in the Ukraine and Russia before and during the Syrian Civil War, and as all aircraft were safely returned, the SyAAF has been able to enjoy a "fresh start".
