Tanya doesn't remember ever hearing about this statue. That's unsurprising; her historical and cultural education in this world is sadly deficient outside of the subjects the nuns thought suitable to little girls, and since she joined the army she spent all her study time on technical topics, so she's basically cheating using her first life's knowledge.
Anyway, she has much bigger concerns to unproductively mull over. Namely: how on Earth was she teleported to Egypt? Why her, why here, why in the middle of a fight that didn't seem to involve her except for a single mage that created a short-range lightning discharge (?) and also a huge dead blue lizard (???)
The lizard could be a papier-mache mockup hidden under the invisibility illusion until she shot it and the caster. A modified flight spell could have kept it up in the air. This is not an explanation, in the sense that Tanya doesn't feel any less confused, but it's something somebody could do, which only leaves the question of why they'd do it. Tanya can't answer that question without knowing what the surrounding fight was about, and she's not about to linger here long enough to try to find out.
The mage holding the lizard could have attacked her with electricity on reflex. Maybe they were just as surprised by her sudden appearance. The unexplained bit is the electricity itself; firstly because Tanya hasn't heard of such a spell and it seems like it should go through a shield; and secondly, because how can you point electricity at a point in midair and not have it go to ground? Well, she doesn't have an actual tool to measure such things; presumably the spell forced it to a given point after which it did ground itself, and the latter step didn't happen to be visible because by then the energy had been distributed over a wide area and atmospheric conditions interfered or something. Electric discharge is instantaneous, so you only see the parts that were momentarily bright enough to form an afterimage on your retina. There, that's explained, and she'll dutifully report to Intelligence about the interesting new combat spell being used in Egypt.
It must be part of their ground-mage doctrine; the Empire has only recently begun the process of conscripting C-grade mages as heavy infantry, and has them direct their magic to shields and strength reinforcements instead of short-range attacks, but the tradeoff with enchanted bullets is a live discussion. Tanya has no idea who is fighting whom, though. The Empire never pushed the Commonwealth colonial border, and it has long since entirely evacuated its remaining forces from the Southern Continent.
That leaves one obvious and crucial impossibility, which is that Tanya was (for lack of a better name) teleported.
She has never heard of it as even a theoretical possibility. If a spell existed that instantaneously moved people and things, it would revolutionize - well, everything. Tanya's mind spins just considering the obvious possibilities. And if someone did invent such a thing, why reveal its existence by using it on her? (Without killing or capturing her in the process?) Even if the rest of her unit was taken out in similar fashion, she's on her way back home to report!
Her orb recorded many different entirely unfamiliar magical spells at the fight. That shouldn't be possible. Even aside from everything else, it would represent a colossal failure on behalf of Imperial Intelligence.
Tanya will go home and find the rest of her unit alive and well hand over the recording to someone more qualified to deal with this headache. She wouldn't wish this on Visha's friend in Intelligence, so it might be Dr Schugel again... well, that's daydreaming. On she flies.
