HG OZ-06MS Leo 1/144

Great Kit, would reccoment to buy :)

The Gundam Wing Leo is one of the most recognizable grunts from all of the shows, behind a few classic like the Zaku and GM's.

The kit is deliberately cheap and designed to be easily assembled, even in large quantities, so you can make a Leo army to face off against your protagonist Gundam suits.
Included is a "105mm rifle" which is a drum fed machinegun, a shield that equips onto the shoulder, but can also be held in the hand (or only in the hand), as well as two beam saber hilts that slot into the shield (and 2 beam saber effect parts).

For variety, I recommend the P-Bandai Leo Full Weapon Set which includes a Leo and a ton of weapons and optional parts, so you can have a fully customized squad.

The ankle armor on these come off really easily, but they don't fall off the model, they just pop out of their ball socket and hang around the foot. This can be really annoying when posing, but it's not a loss risk. Somewhat fixable by giving the ball joint a layer of thickening agent of your choice (such as superglue).

Ultimately the details are really good as the design of the grunt is meant to be simple. Its articulation is also simple, but effective as nothing really gets in the way of itself.
