Anyway, this suit would not do well in open combat zones. It is designed for boarding ships. Meaning it is best used in close-quarters situations where using things like anti-vehicle weapons and PGMP/FGMPs is a incredibly bad idea.
By which he presumably means that the actual armour value is pretty guff.
The vehicle manual battle dress can fill slots with a variety of things, increased strength bonus being one of them. As noted, it costs an *ing fortune.
One thing to note - is this standard, heavy or superheavy battle dress? Superheavy battledress is not going to fit down standard ship corridors (or at the very least, is going to incur a massive DEX and movement penalty for the cramped space)
Ripping open a bulkhead hatch is, I believe, listed in the book - the strength DM for forcing an iris is one of the examples.
Smashing a solid bulkhead - more guesswork, I'd say. Getting through involves not just punching through the wall, but ripping away any machinery or ductwork behind it and creating a large enough gap to fit through.
An assault cycle is the size of a contemporary bike. Smashing it to pieces probably represents the same amount of destruction as making a breach between decks or compartments large enough for a person to move through easily, which is 2 hull and 1 structure - or three vehicle-scale points of damage (call it 12 points of damage in excess of the armour value)
Armour-wise, a ground car or air-raft - something not particularly armoured but structurally sound - seems about right for an unarmoured interior wall, which is armour 6. For any walls which are more structurally integral, 12-18 is 'light military' levels of armour (ATV/IFV).
