打擊直升機、低空飛機、無人機、地面裝甲目標，裝載於T-55AM戰車/豹2A4主力戰車底盤，神射手防空系統（ItPsv 90）

神射手防空系統（英語：Marksman anti-aircraft system）是一款由馬可尼電子系統所研發的英國防空武器系統，主要部件包含一個砲塔，一具馬可尼400型防空雷達，以及兩門瑞士製奧瑞康35公釐機砲。神射手防空系統在引擎表現、載彈量以及有效射程等方面與德國的獵豹式防空戰車十分類似。神射手防空系統的砲塔可以被安裝至許多不同戰車的底盤上，進而成為自行防空火砲。該系統目前唯一的用戶是芬蘭陸軍；該國於1990年向英國訂購了7套神射手系統。芬蘭所使用的神射手系統被裝載於波蘭的T-55AM戰車底盤上，並被芬蘭軍方賦予ItPsv 90（芬蘭語：lmatorjuntapanssarivaunu 90，意為90式防空戰車，其中90代表服役年份）的代號。神射手防空系統被認為是一款非常準確的防空火砲系統，有紀錄的平均命中率約為52.44%。
Marksman is a British short range air defense system developed by Marconi, consisting of a turret, a Marconi Series 400 radar and two Swiss Oerlikon 35 mm anti-aircraft autocannons. It is similar to the German Gepard system in terms of engine performance, ammunition carried and effective range of the ammunition.The turret can be adapted to many basic tank chassis to create a self-propelled anti-aircraft gun. The only known major operator of the system to date is the Finnish Army, which ordered 7 units in 1990. The turrets were fitted on Polish T-55AM tank chassis. The system is known as the ItPsv 90 in Finnish service (Ilmatorjuntapanssarivaunu 90, Anti-Aircraft tank 90, the number being the year the tank entered service). It is considered a very accurate anti-aircraft artillery system, having a documented hit percentage of 52.44%.
