A giant laser shaped like a mortar cannon emerges from a tunnel.

PapalMercenary: Gainax has used tokusatsu references before and since Eva, so it makes me wonder if this scene here with the self-propelled mortar was inspired by a similar scene from the second film in the Gamera series, Giant Monster Duel: Gamera vs. Barugon (1966). In the film, the monster Barugon attacks Osaka with a freezing mist it sprays from its tongue. The JSDF can't get close enough to attack Barugon, since they'll just get frozen by his mist, so they prepare to fire a bunch of missiles at him from the opposite side of a lake. Unfortunately for them, Barugon also has a long-distance rainbow beam that shoots out of his back, which he uses to completely destroy the missiles before they even fire.
