_Can America land troops in Algeria R1? _
Yes, using the 2 transports in SZ10.
A Ger sub in SZ11 doesn’t get a suprise attack on a Transport as it moves by to unload in SZ 12?
Indeed, it doesn’t. The transport never sees the submarine.
_If a destroyer is escorting the transport will they both have to stop and do combat? _
Yes, since all combat occurs at the same time, you cannot first conduct combat with the destroyer, and then move the transport through that seazone to do an amphibious landing.
You can, however, use the destroyer to conduct combat in that seazone, and afterwards move the transport through if you use the transport in the non-combat move.
_We use AA guns in combat. It always gets the gift of the first wound in combat. After combat the AA gun is placed back in the country under control of the victor. Are we doing this right? _
You’re not using it right. The AA-gun can only move in the non-combat phase, so you cannot take it to any combat.
If a territory with an AA-gun is attacked by aircraft, it does get first strike as you mentioned, but it fires only once, at the beginning of the battle.
