=== Armoured cloches ===
There are several kinds of armoured cloches. Cloches are non-retractable turrets. The word ''cloche'' is a French term meaning ''bell'' due to its shape. All cloches were made of alloy steel.
* The most widespread are the '''[[GFM cloche]]s''', where ''GFM'' means ''Guetteur fusil-mitrailleur'' (machine-gun sentry). They are composed of three to four openings, called crenels or embrasures. These crenels may be equipped as follows: [[light machine-gun]]s, direct vision blocks, binoculars blocks or {{convert|50|mm|in|abbr=on}} mortars. Sometimes, the cloche is topped by a periscope. There are {{formatnum:1118}} GFM cloches on the line. Almost every block, casemate and shelter is topped by one or two GFM cloches.
* The '''[[JM cloche]]s''' (''jumelage de mitrailleuses'' or "twin machine guns") are the same as the GFM cloches except that they have one opening equipped with a pair of machine guns. There are 174 JM cloches on the line.
* There are 72 '''AM cloches''' (''armes mixtes'' or "mixed weapons") on the line, equipped with a pair of machine guns and a {{convert|25|mm|in|1|abbr=on}} anti-tank gun. Some GFM cloches were transformed into AM cloches in 1934. (The aforementioned total does not include these modified cloches.)
* There are 75 '''[[LG cloche]]s''' (''lance-grenade'' or "grenade launcher") on the line. Those cloches are almost completely covered by concrete, with only a small hole to launch grenades through for local defence.
* There are 20 '''VP cloches''' (''vision périscopique'' or "periscopic vision") on the line. These cloches could be equipped with several different periscopes. Like the LG cloches, they were almost entirely covered by concrete.
* The '''[[VDP cloche]]s''' (''vision directe et périscopique'' or "direct and periscopic vision") are similar to the VP cloches but have two or three openings to provide a direct view. Consequently, they were not covered by concrete.
