-The '''{{Specs|name}} / Long 12 cm SPG''' ({{Annotation|長十二糎自走砲|Chō Jūni Senchi Jisōhō}}) was a one-off prototype was made with a 12 cm cruiser gun placed on the hull of a Chi-Ha to provide firepower in the defence of the Japanese homeland if the Americans invaded.
+The '''{{Specs|name}} / Long 12 cm SPG''' ({{Annotation|長十二糎自走砲|Chō Jūni Senchi Jisōhō}}) was an obscure, one-off prototype discovered by US Marines at the Yokosuka Naval Arsenal, with little information available on its development. It was created by the {{Annotation|1st Section|Cannon & Artillery}} of the Imperial Japanese Navy Technical Department and assembled at Yokosuka. The vehicle was essentially a stripped-down Chi-Ha hull, modified with a metal platform extension to accommodate the gun crew, and fitted with a surplus 12 cm/45 10th Year Cannon, typically used on cruisers, carriers, or as coastal batteries. With little concrete development history, accounts from testing crews and US evaluations suggest the vehicle was at the limits of what the Chi-Ha hull could handle. All internal modules were removed except for the driver’s position, and the hull was reinforced with automotive steel to withstand the massive recoil of the gun—a force that would have otherwise destroyed a standard riveted Chi-Ha. The vehicle offered no real protection for the crew, leaving them entirely exposed.
-It was introduced in [[Update "Raining Fire"]]. This tank was primarily built around the gun to mechanize it with little consideration to combat protection. Hence it should also be played as it was designed, hunkering down in a protected sniper position, take a shot, and duck for cover until the next shell is loaded.
+It was introduced in [[Update "Raining Fire"]]. Despite being built on the Chi-Ha hull, this vehicle was not truly considered a tank, even within its limited development circle. Instead, it should be regarded as a mobile gun emplacement. The crew is entirely exposed, and the mobility is compromised due to the heavy gun. Sniping is the only viable strategy, with the need to retreat into cover after each shot to maximize survivability. The powerful 120 mm SAPCBC-HE shell, with a velocity of 825 m/s and penetration of 100 mm at approximately 300 meters, defines the Chi-Ha Long Gun as the epitome of a "glass cannon." However, after firing, the gun's severe recoil will likely knock it off target, requiring readjustment if it hasn't already destroyed its target.

	This gun shouldn't be confused with the one on the [[Chi-Ha Short Gun]], while said Chi-Ha has a short gun meant for transport ships on anti submarine & close range fire range, the 12cm/45 10th Year was used as coastal emplacements and outfitted on early Japanese cruisers. It offers a high velocity gun to fling HE over the map with quite an ease.

		+
		+	The 120mm cannon offers two ammunition types: a normal HE and an SAPCBC shot. It is highly recommended to only carry maximum SAPCBC, since you will need to make the 10 rounds count. besides, the SAPCBC has nearly the same equivalent of TNT in explosive filler, meaning that it will react the same way as HE upon hitting the groung or failing to pen.

-While the hull and engine are the same, most non-essentials were scrapped from the Chi-Ha 12cm to reduce weight so the main gun wouldn't weigh an additional toll to the hull. After removing the turret, radio equipment, MG's and cuts in the hull, the tank comes down to almost the same weight of a regular [[Chi-Ha]] and performs hence the same.

 === Modifications and economy ===
 As a glass-cannon sniper with hefty reload, modifications are down to personal preference, either get engine performance upgrades to get to a sniper spot sooner or get the gun upgraded so aiming it down on a target doesn't take too much time.

 '''Enemies worth noting:'''
 * [[M4A3 (105)]]: This low-rank Sherman has strong enough frontal armour, to withstand a 120 mm shell. Try shooting at the turret around the gun mantlet. It won't be easy, but a successful hit will reward you with a knock out.
 * [[KV-1 (L-11)]]: This heavy tank could be a hard nut to crack for the LG if faced frontally. When the KV-1 is unangled, try to shoot the driver's port or the armour on the gun mantlet. When angled, shoot the armour near the gun mantlet only.
