The right one is eerily similar to the ballistic shield (⬇⬅ ⬆⬆➡) so maybe a ballistic wall or something like that? It’s definitely something stationary because there’s no equipment with input shorter than 5.

Don’t really have an idea what the left one might be. The only one that seems close to it is the Quasar Cannon (⬇⬇⬆⬅ ➡) so I don’t know, maybe some sort of a laser sentry? Quasar sentry?

Anti-tank mines maybe?
