LG refers to Lance-Grenade (grenade launcher). Unlike other cloches such as the GFM or the JM, the LG cloche was effectively "blind", possessing a single shuttered orifice in diameter in its flat crown. It had no observation ports at all, as it did not project appreciably above the surrounding surface. The LG cloche came in three models: a small version, high, a large version, and a cloche for two persons, tall. All were in diameter. LG cloches were usually found in the vicinity of an entrance block.
