 While many of these vehicles feature the composite armour permanently integrated with the vehicle, the Japanese Type 10 and Type 90 Kyū-maru MBTs, French Leclerc, Iranian Karrar, Turkish Altay, Indian Arjun, Italian Ariete and Chinese Type 96/98 and Type 99 tanks use a modular composite armour, where sections of the composite armour can be easily and quickly switched out or upgraded with armour modules.The adoption of modular composite armour design facilitates far more efficient and easier upgrades and exchanges of the armour.Soviet/Russian main battle tanks such as T-90s T-80Us and the Chinese Type 96/99s use composite armour in tandem with explosive reactive armour (ERA), making it hard for shaped charge munitions such as HEAT projectiles and missile warheads to penetrate the frontal and a portion of their side armour.
