The Type 90 was Japan's main artillery piece throughout the Second Sino-Japanese War, and later during the rest of WW2. It is a 75mm quick-firing gun-howitzer, lighter but just as effective as its contemporaries, and easily transportable through sea lift. It served faithfully in the Imperial Japanese Army, earning a very good reputation, both with them and with the enemy. After the war its small calibre became a liability, and most stocks were sold off or destroyed.

Shadow Gunnery - Japanese Artillery (WW2)
When the war turned against them, Japanese artillerymen learned to conceal their positions; their pieces stuck out from hidden mountain tunnels, camouflaged lairs and covered-up foxholes, only opening up with a dreadful barrage when the time was right.
EFFECT:
Until this weapon fires, the enemy suffers from a Very Hard DM to their hit rolls against it or the vehicle it is mounted on.
This effect is army-wide; once one weapon with Shadow Gunnery fires, the effect is nullified for the entire army or fleet.
