I Want You to Create a Handgun but You Give Me a Mechanical Armor Instead

#mecha creation
Rayen was transmigrated to a world where he was in the army as an equipment creator. He had also received a legendary weapon system.
When he received a mission to create handguns, Rayen created a mini electromagnetic cannon with his system.
After seeing the tank got completed destroyed by the mini cannon, the general scolded, “Didn’t I ask you to make a handgun? What the heck is this electromagnetic cannon?”
“Sir! Didn’t you request me to create a small, quiet, but powerful weapon? I was just following your order!” Rayen replied.
When his country was going to participate in a military exercise with another country, they needed extra bulletproof vests, but Rayen created military-grade exoskeletons instead.
After seeing their army totally destroying the other country, the general scolded once again, “I asked you to create a couple of bulletproof vests! What the heck are these exoskeletons?”
“Sir! The request was to make a lightweight but powerful armor! Isn’t this what you wanted?”
When they needed single-man combat vehicles to deal with terrorists, Rayen created mechanical armors instead.
The terrorist group could only surrender right away. “What the hell are those armors? Are we in a sci-fi movie? How are we supposed to fight you?”
The general could only glare at Rayen this time.
“Sir! You needed a combat vehicle that has multiple functions, right? The flight-capable armor is the answer!”
