SD:Churchill OP (140mm)

 is a British Artillery unit. It is a Churchill tank converted into an Observation Post, directing BL 5.5-inch Medium artillery guns onto German troop concentrations. This is the same calibre gun also employed by the Sherman V OP and the Cromwell IV OP. While these field artillery guns do not pack the biggest punch, they provide rapid and reasonable artillery power by units that are reasonably well-protected for an artillery observer. The Churchill OP is fielded by the 15th infantry, augmenting its artillery capacities.

Overview
The Churchill OP is a Churchill converted to an observation post, directing off-map BL 5.5-inch Medium Gun Artillery to a given location. BL 5.5-inch Medium Gun were organized into Medium Regiments each with 8 guns. These Medium Regiments were organized into Army Group Royal Artillery.

Strategy
The Churchill OP might not provide the most powerful artillery, but it is still capable of decimating and pinning down infantry and other soft targets, especially considering the high rate of fire of the artillery strikes.

The Churchill itself is still somewhat useful after depleting its strikes, as it is armed with machine guns and has enough armour to withstand some punishment. In destruction mode, though, the player should be cautious in committing the Churchill OP to the front lines, as its destruction will still result in a costly 120 points to the enemy. As with all artillery observers, only three barrages (emergence - fire-for-effect - precision) can be directed. Once exhausted, the artillery observer unit can no longer order artillery strikes and this cannot be replenished.
