If the Green Beret is switched away from during "Betrayal" with the M1 Garand with Grenade Launcher equipped, the AI can actually rapid-fire grenades in a semi-automatic fashion.
If you pick up a Kar98K during Betrayal, you can actually launch grenades with it, I don't think you can do this in other levels.
While I've not done a full playthrough of it, the PS2 (No idea about the original Xbox version) Version of Strike Force has differences:
Gestapo have Red Arm Bands.
M1 Garand is missing entirely, instead the Green Beret starts Betrayal with a Kar98K instead and there's no Grenade Launcher Alt-fire.
The Shotgun is also missing entirely, instead an MP40 takes it's place in Cold Reception.
There is an extra difficulty, "Commando", you need to get 5 stars in every mission to unlock it, in addition, difficulties will actually still effect enemy placement like in C2.
In addition, Difficulties effect weapons, for instance, "Wolf's Den" will start with the Spy with only his Piano Wire on Commando as opposed to having a silenced pistol like other difficulties, I'll have to test to see all the levels that are effected, as well as if weapon pick-ups in the environment change.
There's an extra weapon not listed on Commandos HQ, an unmounted MG42 the Green Beret can carry around (Like in C3), it doesn't have infinite ammo and needs to be reloaded, it's in Betrayal, in the same sorta hut with an mounted regular MG42, , it can also be found in Panzers! in the house with an MG42 mounted. (near where the STG44 is) , in addition an trailer depicts it being used during the final mission but I'm fairly certain you can't obtain it there in the final game. (Same thing with Beta Screenshots showing Molotovs in Panzers! or the Green Beret in Behind Enemy Lines.)
In addition, on Commando difficulty, the portable MG42 in "Betrayal" is gone while on Hard/Commando the Portable MG42 in the MG42 house near the documents/STG44 is gone on Panzers!.
Playing on at Easy will double the amount of pistol ammo you can hold.
If you throw a smoke grenade and it lands next to some enemies, they'll start choking on the smoke, it won't kill them but it will prevent them from firing back.
If there's any other lesser known/undocumented information about Strike Force that's not here, feel free to mention them.
