By Kris Osborn, President, Center for Military Modernization Iran’s call for the destruction of Israel is an extremely public and well known reality, a loudly professed position which raises a number of questions regarding Iranian and Israeli military capabilities, their respective weapons arsenals and level of tactical proficiency. Just what might happen in a war between Israel and Iran? There are always so many unknowns in war, and assessments and wargames may often miss the mark regarding the tactical combat circumstances which ultimately transpire …. Yet there is much relevant detail related to these questions which can be learned or at least evaluated. Many public Iranian documents, philosophies and remarks from senior civilian and military leaders incite the possibility of violence as a means to achieve this stated goal of Israel’s demise. As far back as several years ago, the leader of the Iranian Republican Guard Corps, Maj. Gen. Hossein Salami, claimed “Israel could be blown up in a single operation.” What might sound like reasonably typical inflammatory anti-Israel rhetoric coming from Iran, could actually reflect Iran’s interpretation of how an Israel-Iran conflict might unfold. Assuming Gen. Salami’s comments were not related to the use of nuclear power or related to Iran actually possessing a nuclear weapon, they raise the question of force size, tactical proficiency and weaponry related to a potential Iran vs. Israel conflict. Israel vs. Iran in the air An initial question is simply one of geography, meaning the prospect of each country having success attacking the other. While Iran is known to fly some older fast and highly capable F-14 Tomcats, it is not clear how well maintained they are and Iran is quite likely extremely vulnerable to Israeli fighter jets in the air. Tomcats are fast, but likely to lose quickly in any air confrontation with 5th-generation aircraft simply due to sensor and weapons ranges. Israel, for instance, operates a fleet of 5th-generation stealth aircraft to include its F-35i Adir variant, likely capable of achieving air superiority and eluding Iranian air defenses. Iran is known to operate some Russian-built air defenses, yet it is by no means clear they would be able to detect and destroy Israeli F-35is. In terms of sheer numbers of fighter jets, Israel has a relevant advantage of more than 50 aircraft, as Globalfirepower.com 2023 rankings reports that Iran operates 160 aircraft compared with Israel’s 241. However, the critical question here likely pertains to an issue of technological superiority, given that a single 5th-generation F-35 has shown in multiple wargames that it is capable of using long-range, high-fidelity targeting sensors and advanced weapons to destroy a much larger number of 4th-generation aircraft. Any quick analysis of available assets and technologies would suggest that Israel is likely to operate with a distinct advantage over Iran in the air, something which would make it very difficult for Iran to make any lasting progress with a ground invasion. The question of Israeli air superiority also weighs heavily upon the feasibility of Iran being capable of launching any kind of ground invasion into Israel. In order to access Israel, Iranian ground forces would need to travel through Turkey or Iraq or somehow transit the Persian Gulf, all scenarios wherein approaching Iranian forces would easily be seen and be vulnerable to Israeli air attack. Therefore, apart from the concerning prospect of Iran at some point having nuclear weapons, there do not appear to be a wide sphere of ways Iran might actually be able to attack Israel with any measure of success. Unless, of course, Iran were to employ terrorist tactics, something by no means beyond the realm of possibility. In fact, small, covert hit and run types of terror attacks may be the kind of thing Hossein was referring to by hinting that several targeted strikes could bring down Israel. Added to this equation is the well known fact that Iran has been, and likely continues to be, a state sponsor of terrorist organizations. However, just as is likely the case with air defenses, Israel is certainly experienced and likely adept at counterterrorism tactics for obvious reasons. Iranian Ground Army While Iran does, at least on paper, appear to have a larger ground force, particularly when it comes to tanks and armored vehicles, that does not in any way mean that its land force would in any way be equivalent to Israel. Globalfirepower’s 2023 military assessments [https://www.globalfirepower.com/countries-listing.php] for instance, list Iran as having 4,071 tanks compared to Israel’s 2,200 tanks. However, having 2,000 more tanks than Israeli does not by any stretch ensure military overmatch, as sheer numbers of tanks may prove to be much less of an advantage should a smaller tank force be equipped with vastly superior sensors, weapons, computing and targeting. This may well appear to be the case with even a cursory look at how Israel’s well known and highly regarded Merkava tanks would compare against Iranian upgraded Soviet-era T-72s. ARMY 2040 Army Futures Command An interesting report in “21st Century Asian Arms Race,” states Iran has German-built Leopard tanks as well as Russian T-90s [https://warriormaven.com/land/the-russian-army-is-getting-its-first-new-t-90m-tanks] and even some Abrams. Iran’s first widely reported indigenous tank called the Farrar has emerged in recent years, a platform said to be based upon an upgraded Iranian T-72S chassis. The Iranian tank, reported to operate with an electro-optical fire control system, laser rangefinder and ballistic computer, would at least on the surface appear to most likely be vastly inferior to the Israeli Merkava. The Israeli Merkava is among the most advanced armored vehicles in the world. It can carry infantry or injured soldiers, leverage a rear exit hatch for dismounted operations or safety escape and, perhaps of greatest significance, its main gun tube can itself fire anti-tank missiles, according to a report in The National Interest. The Merkava also has top-attack missiles potentially useful for attacking helicopters and other targets potentially out of range for a standard tank shell. What much of this amounts to is simply that even if it operates as many as 2,000 fewer main battle tanks compared to Iran, Israel may indeed operate a vastly superior land force. During the Gulf War’s famous tank battles, for example, U.S. Abrams advanced thermal sights were able to detect, find and then help destroy Iraqi T-72 before they were in range to even be detected or seen by Iraqi tanks. Therefore, large numbers of Iraqi tanks were disproportionately destroyed by far fewer Abrams armed with long-range, high-fidelity targeting sensors. Iran operates nearly 400,000 more military personnel than Israel, as Iran's total force of 1,015,000 is significantly larger than Israel's reported force of 646,000. This difference, however, is not likely to be much of a factor if Iran cannot get in position to launch a ground invasion and operates a largely inferior ground Army in terms of weapons and technology. Iranian Arsenal Iran is reported to operate about 1,000 more armored vehicles than Israel. Iran is listed in the Globalfirepower 2021 assessment as having 8,500 armored vehicles, compared with Israel’s 7,000. Again, any size deficit is likely to be less consequential, unless the technological capacity were in any way comparable. While a lot of details regarding any kind of particular technical comparison may not be available, the advanced technologies built into the Israeli Merkava might make it seem unlikely that Iran has vastly superior infantry carriers and armored vehicles. Furthermore, without superior tanks able to break through the proactive barriers or defensive configurations of an Israeli force, any Iranian advance might be less likely to succeed. Iran does, however, have much more artillery and Multiple Launch Rocket Systems (MLRS) when compared to Israel, yet both traditional artillery and 70-to-80km-reaching MLRS would not be in position to strike Israel unless they were moved close to its borders through forward deployment. At the same time, Iran is reported to operate a large number of Short, Medium and Long-Range Ballistic missiles in position to hit Israel. An examination of Iran’s large ballistic missile arsenal with a mind to guidance and range raises a serious threat possibility to Israel, as Iran appears to now operate at least five different long-range ballistic missiles capable of hitting Israel from Iran. Maps of the Middle East show Iranian missiles are easily able to hit Jerusalem and other parts of Israel from locations throughout Iran, as Jerusalem is less than 2,000km from Tehran. This means some ballistic missiles launched from Iran’s capital can hit Israel and an even higher number of long-range weapons can easily hit Israel from other locations within Western Iran. An interesting and quite significant research paper from Iran Watch [https://www.iranwatch.org/] shows that indeed Iran does possess a massive arsenal of ballistic missiles, at least five of which can reportedly travel distances of 1,300km or more. The famous Shahab-3, for instance, is listed by Iran Watch as capable of traveling 1,300km with a 1,000kg warhead. The liquid fuel, single stage Shahab-3 rocket is now deployed and exists in large numbers. The longest range ballistic missile listed by Iran Watch is the Khorramshahr 1,2, and 4 .. weapons cited as able to travel as far as 2,000 to 3,000km. This means the missile could hit anywhere in Israel from Tehran or most places throughout Central and Western Iran. Other Iranian Medium Range Ballistic Missiles capable of traveling 1,600km or more are the now-deployed Ghadr, Emad and Paveh missiles, according to Iran Watch. The Iranian Sejjil MRBM can travel 2,000km as well. Navy a factor? Neither Iran or Israel have much of a Naval presence, however Iran is known for its ability to launch small boat attacks and is reported by GlobalFirepower to operate as many as 19 submarines, compared with Israel’s 5. Therefore, depending upon what kinds of cruise missiles or land attack weapons Iranian submarines are capable of firing, it is conceivable that Iran could hold critical parts of Israel at risk from waters in the Eastern Mediterranean.
