Yukikaze (originally titled Sentō Yōsei Yukikaze in Japan, translated in the official subtitles as "Battle Fairy Yukikaze") is a five part OVA series from Bandai Visual and Studio Gonzo based on the science-fiction novel Chōhei Kanbayashi.
The following weapons were used in the OVA Yukikaze:
A number of FAF personnel are seen using Glock 17 pistols, suggesting that this is their standard issue sidearm.
The FAF MPs are seen using Calico M100FS rifles, which are inaccurately depicted as being fully automatic.
Fukai uses a FN P90 while aboard the Banshee airborne fortress.
Howa Type 89
Several Japanese soldiers are seen carrying Howa Type 89 rifles in episode 4.
Fictional Assault Rifle
Colonel Rombert's men are all armed with a fictitious futuristic assault rifle. The weapon draws heavily from many of the "futuristic" designs from the late 90s and early 2000s such as the Heckler & Koch XM8 and XM29.

Colonel Rombert's forces use APCs armed with GE M61 Vulcan cannons in front.
GE M197 Vulcan
The APCs used by Colonel Rombert and his men have GE M197 Vulcan cannons mounted on the rear of each vehicle.
