Medal of Honor

It's a GBA, so don't expect FPS.
This is how it looks from above.
There are some shooting-type missions in the middle, but...
Weapons can be changed or refilled with ammunition in a bunker, room, or house that serves as an armory.
And ammunition can be obtained as ammunition-shaped items.
(For some reason, the main weapon and secondary weapon are loaded together. [Gun, grenade])
Submachine guns and pistols have 3 rounds, support weapons have 2 rounds, and rifles have 1 round.
Enemies are killed... but sometimes they are heavy infantry (right?) or elite soldiers.
In this case, you must fire one more shot each. (4 shots from a submachine gun, 4 shots from a pistol, 3 shots from a support weapon,
2 rifle shots)
